How can I make animations for my very own enemy for Amnesia?

You need to import the models into a 3D model editor and edit them from there. Two of the applications you can consider are Maya or Blender.

I just decided to log on and check the forums for the first time in like... 4 years... Romulator is correct! You need to animate the models in Blender or Maya with a skeleton or rig. Save the animation out as a .dae file. Make sure the file actually contains animation. If it doesn't, nothing will show.

(Make sure you click the check box next to "include animation".)

Cheers!
