Yes , up to a point. There are many variations on how a skin shader can be written. I simply want to know for the following you specified what image files and masks go to which parameter .

Diffuse     >   skin texture map   + (a: overlay + mask)

Specular  >   skin map or specular map  + (b: overlay + mask)

ambiant   >    ?    (c: overlay + mask)

bump       >   bump map  + (d: bump overlay + mask)

Displacement > displacement map  + (e:  displacement overlay + mask)

thats up to 5 sets of overlays and masks to add if you are using seperate images and masks for each thing.
