introduction and nooobiequestion

Hi Folks
My name is Patrick, living in Western PA, USA.
I decided about a week ago to teach myself this program. I believe i’ve made pretty good progress (with many distractions), but now am stuck
I’m laying out an architectural model of a campground. Ive made the buildings out of simple cubes, subdividing 2 top edges and raising a roof. now I would like to apply texture images, to make them look like walls and roofs.
The thing is, I’m getting bits and pieces from different tutorials, and at this point i’m just going in circles. No matter what I try I cant get more than one material to apply to a building. ive added materials, ive tried uv mapping with single faces. just cant grasp what im doing wrong. can someone guide me through this?
Thanks for any help you can give me
Pat

Hi and welcome
Have you tried this from the blender manual

If you cant figure it out, you can always post a blend file showing what you have tried so far so, someone can take a look and offer advice based on this.

thanks for your reply
I looked at that manual again and things started to make sense. I think I just needed sleep. I was assigning the texture, but not changing the color, so everything just appeared grey.
