Im at a loss as far as the heads go, but the bodies I would suggest are:
For the white one, the body looks an awful lot like Mace Windu. Maybe the SA Mace Windu would work?
For the Asian one, I actually made a body for another previous custom very similar to this. I used the ROTS Plo Koon and painted the legs white it looked very similar to the Jedi pictured.
Good luck. Those heads may be tough to track down.
PS Who are these people?
