Wikipedia has separate articles on the different ranks, but they are not (as of this writing) systematically categorized. For example: Illustris or Gloriosissimus.
The Illustris article refers to Jones, A.H.M., The Later Roman Empire 284-602, A Social, Economic, and Administrative Survey (Oxford: Blackwell, 1964, repr. Johns Hopkins UP, 1986) which is a famous work and probably has all the information you need.
P.S. Note that the titles shifted meanings over a centuries and often what had been a very high rank would become an almost entry-level designation a few centuries later.
P.P.S. If you search your link of the Notitia for 'illustris' you'll find it all over the place.
