Can someone help me out how this textures work

[Synyster]

I have a 3d model from one rpg game, and i want to apply textures on this mesh but i have problems with transparent parts of the texture, they look white when rendered its something with alphachannel i think but i cant make it work opening fbx model with 3d max i not able to make the background of the texture transparent. Here i uploaded the fbx mesh and 3 textures they all are in dds format. https://gofile.io/d/lx6nak

Those are 3D textures - you will need an application that can combine them all like Blender.
