Problem loading textures for fbx model

Hello everyone, I'm pretty new to Unity so if it is obvious sorry but I'm having trouble using a fbx model I downloaded online. Problem is that on the page where I downloaded the model it looked this way The textures come in a rar pack, problem is that there is more than one while the model has just one component I basically don't know what to do to apply these textures and get a final result at least similar to the one above and can't find anything online, is there a way to get the model as shown in the page above?

I'm trying since days with no clue about what to do, please help
