need help with blp

I want to have two footman .blp in one map but i can only get one blp to work. I've tried importing a footman mdel but one skin only works.
I've seen in many cinematics like TTOA three different villiger skins
how can i do this?

I also would like too know how to do this.. I think it has something to do with creating a new model and changing the texture paths.. As for the villagers.. There are already multiple villagers...
