Anyone knows where I can find free 3d animated character compatibile with unity with this animation (for testing purpose):
idle
walk
sit down
sit idle
stand up
Thanks in advance!
Check out the Platformer tutorial, it has an animated character!
There’s also the character animation examples from the Unity site.

No one of this characters have sit down, sit idle and stand up animation…
You can always make your own animation clips in unity 
Section 1 - The Animation View
An introduction to the Animation View and how to create animations in Unity.

Also, there’s tons of free characters in turbosquid, many of them are rigged so I can animate them, and if you’re lucky you’ll find just the one that suits you!

Wrong section. Not even sure where it’s supposed to go either, which is just sad.
Try the Mecanim Animation Starter Pack. Lot of useful stuff there.
