1.) Gay sports R-R-D (though not 100% on the D) 2.) Formerly in Greece, young men the last to be hip, perhaps -P---I [rab] Really? I thought it was quite easy this week. Or was that from last week? [Big Dave] Permitted?
Afraid I can't help with yours, apart from to suggest that Number 1) does not end in "D" - I have written out all the possibilities, assuming that the missing letters are vowels, and nothing seems to fit the clue. Number 2) may end in "phi" (anag. of "hip"). Sorry I can't be of more assistance.
[MF] I think your last one is EPHEBI - Big Dave was on the right track but it's "the last" (E), then an anagram of BE HIP (PHEBI). These are, according to http://76.1911encyclopedia.org/E/EP/EPHEBI.htm "a name specially given, in Athens and other Greek towns, to a class of young men from eighteen to twenty years of age, who formed a sort of college under state control."
