The Simpsons Game [PS3] Texture Question

[PolyMars]

Hi! I have a question about the textures for The Simpsons Game. Is there a way to paste the textures onto the models all at once instead of doing it one-by-one manually in Blender? When I try to put the textures onto the models in a certain place manually, the texture gets also gets added to another part of a different model which shouldn't be.
