She ain't no "baby" if she's in the Court, but I can easily choose another title if it pleases you. The # are personal files for each and every male, it's just a general number for identification (think about intel files for example) and it doesn't mean anything special. The titles are given to the succubi as a mean to outline their position  at the Queen's Court. Again, it doesn't mean anything special, but it might give a clue on what kind of errands the Queen might send her loyal subject to complete. If they bother you guys, I can scratch them, it really isn't something to fret about.
