Need help understanding what these maps are and how to connect them.

Hi everybody. So my questions are kind of all over the place.
I've been trying to read and watch videos, but I find it hard to find exactly something that helps me with explaining the maps that I have.
So I found a model online to start testing PBR with. I can upload it if it doesn't break the rules.

So I have diffuse, glow, normal, specular and a green one. I'm aware the green map is a combination of different textures all only needing one channel. The G-channel holds the ambient occlusion, but the other two I'm not entirely sure about. I would say that the R is metalness and B is roughness, but I could never produce very nice looking results, treating them that way.
As I've come to understand these are the maps of a specular workflow as the specular map has color information in it.  But the diffuse map is not a complete albedo as there are shadows baked in.

I've tried connecting them in Arnold for Maya, but it just doesn't look as I think it should. Is this something I wouldn't use this aiStandardSurface1 shader for, as it's not built for a specular workflow in mind? I've tried inverting the R and/or B-channel and feeding it into the specular roughness, but nothing really makes it look nice. The reflections aren't coming out that nice.

This all leads me to wonder if I would be able to load in my base maps(diffuse, normal), inside Substance Painter and create new textures for the roughness and metalness to convert it to a metalness workflow?
