What ghostship2 said - to expand a bit, using those maps the setup should be very simple.

Physical root

Plug colour map to colour chip Plug roughness map to roughness chip, set chip value to 1 Plug metal map to metallic chip, set value to 1 Plug normal map to normal chip, set value to 1 (Ignore AO map)

Principled BSDF

Plug colour map to colour chip Plug metal map to metallic chip Plug roughness map to roughness chip Plug normal map to Cycles - Vector - NormalMap node, set strength 1 and space at tangent; then plug into normal chip (Ignore AO map)

Set specular to 0.5 (this means 4% base reflectance for non-metals).

That’s it. Gamma on the maps should be 1 for everything apart from the colour maps. Given the same light and render settings the results should be a pretty good match.

AFAIK AO maps are intended for realtime engines that don't calculate occlusion. They could be useful for adding extra dirt effects, but aren't necessary in Superfly.
