More detailed description is required. Do the 5 sec is a duration of the rapid healing or it is a buff which triggers heal?

5 seconds is the duration of the heal

Use footmans to attack other footman to trigger the effect.
To change healing parameters move to USE ABILITY trigger and set all you need. Range of ability must be slightly higher than range in object editor.
