I have walls of paper, for this model, I want to know if you can use different textures in the same lane, for example using a brick texture on the outside of the face, and a white texture on the inside of it face ???
Same as above but using Blender Render - it has to use nodes, there isn't a way without it. By using the Geometry node, I plug the Front/Back input to the Factor of the color mix node that is sent to the material color node. At this stage, you can then plug your image textures into the two colors of the color mix node, and indicate the UV Map name there in the Geometry node.
