There is this site where you can get materials
If you click whatever you like this shows up

There are 5 different photos usually, which somehow you need to combine to get the material.
How do i combine them?

You are in the wrong sub-forum.
Search out some tutorials for creating materials, and read about material properties in the documentation here:
