Trying to use multiple png files for a single texture

Im trying to use a 3D model I found online for my player in a game Im making, but it came with a lot of png files for textures instead of a few, and I don't know how to combine them to use them as a single texture for the model, should I try to texture atlas it, or do I have to spend a long time UV mapping it in photoshop or something in order to do it?
