can some one teach me how to fix these?

It means that there's no valid keyframes for certain manipulations, for example it says "scaling" for certain bones, it means that there's no scaling data in the first and last KFs of the mentioned animations, you can just scale something back and forth to get it, still this is not an issue you should worry about, unless it shows up ingame.

@Maximal I really new with tis things... its really hard for me to understang it...

@kangyun you just scale/rotate the mentioned bones in the mentioned places by 0.1 and back, that will do it I think.
