in your trigger Loop you are already picking up enemy units when the spear moves and hits something so to make sure you (stunned and knockback) correctly then try add the unit to a unit group
try something like Unit Group - Add (Picked unit) to Remilia_Hit_UnitGroup
for the stun you need a dummy to stun so try something like
Unit - Create 1 Dummy Caster for (Owner of Remilia_Cast_Unit[6]) at (Position of (Picked unit)) facing any angle
Unit - Add Storm Bolt to (Last created unit)
Unit - Order (Last created unit) to Human Mountain King - Storm Bolt (Picked unit)
Unit - Add a 1.00 second expiration timer to (Last created unit)
and then we come to Knockback i can see in your trigger you are trying to move (Picked unit)
but outside the picking loop (Picked unit) it becomes invalid so
instead you should store hit units in a list or array so you can reference the unit
you can do something like
Set TempPoint = (Position of Remilia_KnockTarget[what you use])
Set Knock_Angle = (Angle from (Position of Remilia_SEN_Dummy2[1]) to tempPoint)
Set New_Position = TempPoint offset by 25.00 towards Knock_Angle degrees
Unit - Move Remilia_KnockTarget[what you use] to New_Position
You can run this over a duration that is controlled by Remilia_KnockDuration
and you can increase the offset per tick for smoother knockback if you like
in your trigger Loop you are already picking up enemy units when the spear moves and hits something so to make sure you (stunned and knockback) correctly then try add the unit to a unit group

Unit - Move Remilia_KnockTarget[what you use] to New_Position
You can run this over a duration that is controlled by Remilia_KnockDuration
and you can increase the offset per tick for smoother knockback if you like
Add to you knockback list (Remilia_KnockTarget) ad the start of knock loop
and is a unit array .... so for this we to count units ass well
so in your Remilia_SENReleased Loop we set
Remilia_KnockTarget[1] = Unit A
Remilia_KnockTarget[2] = Unit B etc etc etc is how you store them is when the spear hits enemies
we also set this 2 .... -> KnockTarget is unit array and KnockCount is integer
Set Remilia_KnockCount = Remilia_KnockCount + 1
Set Remilia_KnockTarget[Remilia_KnockCount] = (Picked unit)
and in your knock loop set
For each (Integer i) from 1 to Remilia_KnockCount, do (Actions)
Loop - Actions
we Move the Remilia_KnockTarget toward the knockback direction
and
For each (Integer i) from 1 to Remilia_KnockCount, do (Actions)
Set TempUnit = Remilia_KnockTarget we Move the TempUnit toward the spear direction
so let break it down
first Variables
Remilia_KnockTarget (unit Array) .. Remilia_KnockCount(Integer) .. Remilia_KnockDuration (Real) .. TempUnit (Unit) .. TempPoint (Point) ..
SpearPoint (Point) .. NewPoint. (Point) .. KnockbackAngle (Real)
then trigger Remilia_SEN Knock Loop
Remilia_SEN Knock Loop
Event
Time - Every 0.03 seconds of game time
Condition
(Remilia_KnockCount Greater than 0)
Action
Set Remilia_KnockDuration = (Remilia_KnockDuration + 0.03)

Loop - Actions
Set TempUnit = Remilia_KnockTarget
Set TempPoint = (Position of TempUnit)
Set SpearPoint = (Position of Remilia_SEN_Dummy2[1]) or 2 depens if you are using both
Set KnockbackAngle = (Angle from SpearPoint to TempPoint)
Set NewPoint = TempPoint offset by 15.00 towards KnockbackAngle degrees
Unit - Move TempUnit instantly to NewPoint
Special Effect - Create a special effect at TempPoint using Abilities\Spells\Items\AIfb\AIfbSpecialArt.mdl or what ever you like here
Special Effect - Destroy (Last created special effect)
I hope you could elaborate more on the purpose of this spell. What does it do exactly? I can only guess from the code for now. So your goal is:
You want the caster to channel for X seconds
After channeling for X seconds, the spell will summon a spear?
The spear will then travel for X distance
Enemies that got hit by the spear will get a knockback effect for X duration?
Please correct me if I assume incorrectly.
This is quite an ambitious goal for a start, but I like the spirit!
Get ready for a wall of text!
Please read the trigger comments as well for a better understanding of things!
Configuration Trigger
First, I prefer to keep every "configurables" in a separate trigger dedicated only to configuration-related things. I will call it "Impaling Spear Config" trigger. This trigger will only run once when the map is loaded, to do so we can use "Map Initialization" event.

Main Trigger
Now, we can start with the trigger that actually runs when we cast the spell! You don't need to use array variables at all, let's keep it simple by using only normal variables so you don't have to worry about arrays! Also, do not use waits, as they are imprecise and tend to cause troubles along the way.
In order to do this, we will use the event "Unit - A unit Starts the effect of an ability" which runs right when the ability is casted.
The condition is "(Ability being cast) Equal to ImpalingSpear_Ability", which uses the variable we declared earlier in Impaling Spear Config trigger.

-------- - --------
Set ImpalingSpear_Unit = (Triggering unit)

-------- < INSERT WHAT YOU WANT TO DO HERE > --------
-------- - --------
-------- Now that we are done, we can continue to the next trigger --------
-------- There are many ways to do a "loop" --------
What is Loop Trigger?
A loop is basically a repeating code. For this context, we will be using a repeating timer as a loop. There are two ways to do it. You can do it just like how you did before, something like this:
Impaling Spear Loop
Events
Time - Every 0.03 seconds of game time
Conditions
Actions
-------- Do your actions here --------
-------- When you're done, you can pause the timer like this --------
Trigger - Turn off (This trigger)
However, the downside is we cannot alter the value directly on the event so we cannot use our previously declared variable "ImpalingSpear_Interval". Luckily, there is a workaround for that, we can use "Trigger - Add New Event" function to the "Impaling Spear Loop" trigger. To set it up, we need to go back to our "Impaling Spear Config" and add another line of code just like this.

Loop Trigger
Now, we are ready to code the logic for the delay (preparing the spear before throwing it) and the movement of the spear after it is thrown. First, we need to check if the caster is still casting the spell. We want the spell to be cancelled if the caster is interrupted during the waiting phase.

-------- We must check: --------

-------- * The unit belongs to the caster's enemy --------
-------- * The unit is not dead --------
-------- * The unit is not in already damaged group --------
-------- - --------
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
((Picked unit) is A structure) Equal to False
((Picked unit) belongs to an enemy of (Owner of ImpalingSpear_Unit)) Equal to True
((Picked unit) is dead) Equal to False
((Picked unit) is in ImpalingSpear_AlreadyDamaged) Equal to False
Then - Actions
-------- - --------
-------- The unit fits our criteria! --------
-------- Let's deal damage to them using our previously declared value --------
-------- "ImpalingSpear_Damage" variable from Impaling Spear Config Trigger --------
-------- - --------
Unit - Cause ImpalingSpear_Unit to damage (Picked unit), dealing ImpalingSpear_Damage damage of attack type Spells and damage type Normal
-------- - --------
-------- The unit is damaged, let's mark it by inserting it into a unit group --------
-------- This way, the enemy unit will only take the damage once --------
-------- We can also use this group to do a knockback --------
-------- - --------
Unit Group - Add (Picked unit) to ImpalingSpear_AlreadyDamaged
-------- - --------
-------- You can create a special effect here if you wish --------
-------- Destroy it right away as we no longer need it --------
-------- - --------
Special Effect - Create a special effect attached to the chest of (Picked unit) using Abilities\Spells\Other\Stampede\StampedeMissileDeath.mdl
Special Effect - Destroy (Last created special effect)
-------- - --------
-------- Handling a knockback takes extra effort --------
-------- You need to learn "Dynamic Indexing" or "Hashtable" first --------
-------- If you want to make your own knockback system --------
-------- - --------
-------- Luckily for you, we have many Knockback System to choose from in Hiveworkshop --------
-------- For this, I will use Bribe's knockback 2D --------
-------- - --------
-------- First store the position of the enemy unit --------
-------- - --------
Set ImpalingSpear_EnemyPoint = (Position of (Picked unit))
-------- - --------
-------- Then you need these four variables: --------
-------- - --------
Set Knockback2DAngle = (Angle from ImpalingSpear_DummyNextPoint to ImpalingSpear_EnemyPoint)
Set Knockback2DDistance = 500.00
Set Knockback2DTime = 1.00
Set Knockback2DUnit = (Picked unit)
-------- - --------
-------- Then simply run the Knockback 2D trigger --------
-------- - --------
Trigger - Run Knockback 2D <gen> (checking conditions)
-------- - --------
-------- This does not stun them, so you have to create another dummy and order it to cast stun ability at these units --------
-------- This will be an example: --------
-------- - --------
Unit - Create 1 StunDummy for (Owner of ImpalingSpear_Unit) at ImpalingSpear_EnemyPoint facing Default building facing degrees
Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
Unit - Order (Last created unit) to Human Mountain King - Storm Bolt (Picked unit)
-------- - --------
-------- This will create a dummy that cast a storm bolt to stun --------
-------- For every enemy unit --------
-------- Which means, if you pick 10 enemies, you will create 10 dummies --------
-------- Not very ideal, ideally you want only one dummy and order it again and again. --------
-------- You can achieve that by creating the dummy for neutral passive at config trigger once --------
-------- Then you can order that dummy to cast storm bolt here --------
-------- - --------
Else - Actions
-------- - --------
-------- Let's check whether the dummy unit has reached maximum distance or not --------
-------- We can achieve this by comparing CurrentDistance to MaximumDistance --------
-------- - --------
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
ImpalingSpear_CurrentDistance Greater than or equal to ImpalingSpear_MaxDistance
Then - Actions
-------- - --------
-------- It has reached the maximum distance --------
-------- Let's kill or remove the dummy unit --------
-------- - --------
Unit - Kill ImpalingSpear_Dummy
-------- - --------
-------- Don't forget to clear the "AlreadyDamaged" group, so it can be used again next time --------
-------- - --------
Unit Group - Remove all units from ImpalingSpear_AlreadyDamaged
-------- - --------
-------- This trigger is now finished, let's turn it back off --------
-------- - --------
Trigger - Turn off (This trigger)
Else - Actions

Now, this works perfectly and aligns with the goal I assumed earlier. Hopefully, I assumed correctly, I spent time writing this, lol.

You should check the testmap that I attached, you can see the object editor as well to see how I set up things.
The code I have written is actually very far from perfect.
It is not leakless, you can read it here for more details -> Memory Leaks
It is not MUI, meaning it will not work properly when casted by multiple units at the same time. For a start, you can read this -> Visualize: Dynamic Indexing
It creates dummy for each damaged enemy (dummy caster should be created once and reused).
Some constants are not written in the config trigger. For examples: Area of Effect, KnockbackDistance.
Adjustments are absolutely necessary as the spear spawns and thrown before the animation is properly finished.
I highly recommend reading and learning about Dynamic Indexing or hashtable first for a better understanding of MUI.
I am writing this as a Non MUI spell so you can get a better understanding of how the trigger logic work using what you already know.
Hopefully, it is helpful for you and the readers.
Your next task is to read the tutorials from the link that I gave you and try to make a MUI version of this spell.
Good luck! and feel free to ask!
