model textures not fully covered

First off I'm new to this and only the models to look at for reference in propmaking.

I've downloaded some KH1 keyblade models and looking at them in Noesis, and each includes an OBJ file and some PNG textures. The OBJ files aren't fully covered in the textures and I can only see the complete outline of the model by using the cycle blend option.

Is there a way for me to apply or assign the textures to the model so I get a complete image?
