The texture maps included in the hair are intended for a different rendering model. You can do what you did to kinda find the right slots to put them in, but for the best effect they will need to be modified for the particular hair system you are using. I am not really sure where to begin, as Hair usually has a different material for every single rendering style. It might be easier to “render” the good hair from Daz onto a low poly set of hair and textures. Or not. You could try it, and see if that gives you the effect you want.
