Ive noticed that some guitars have names after them like special, standard, custom. Is there any rank that goes with these names.

judging by these 'ranks', I guess you were looking at Gibson guitars.

In that case, it goes (worst --> best)
special --> studio --> standard --> custom

When Gibson calls something "special", it's special in the way a retarded kid is.
