Combine Fbx with meshes

I’m pretty new to using UE4, especially importing fbx files with textures from different sites. I purchased a scifi looking vending machine that comes with textures. I import the file into Unreal. How do I get the textures to combine with the fbx model correctly to look like the finished product seen on the different sites? I’ve tried putting the fbx file into the same folder as the textures and importing. That doesn’t work. I’ve read multiple posts on here and have watched a lot of videos. Nothing seems to work. Do I have to manually go into the blueprint and connect the nodes?
