9. Raven – bird. Beginning to nod (N) after wild party (RAVE).
10. Inelegant – ungraceful. Anagram (new) of AGENT IN and (L)aussann(E).
12. Eleven – team. Even (EVEN) with ‘the’ in Spanish (EL) put first.
13. Minion – flunkey. Short garment (MINI), worn (ON). I half wondered if minion could also mean a short garment or a garment with the final letter missing but then I saw the word play.

18. Rabbi – Jewish scholar. Rhode Island (RI) holding a (A) and couple of bishops (BB).
19. Indo-China – Asian peninsula. My brief researches have only found this word un-hyphenated and defined as a peninsula in SE Asia, between India and China consisting of Myanmar, Thailand, Laos, Cambodia, Vietnam and Malaysia. Trendy (IN) and mate (CHINA) holding party (DO).
21. Tweak – jerk sharply. (T)oo, feeble (WEAK).

3. Eagle – bird of prey. Endlessly keen (EAGEr) circling lake (L).

6. For the asking – gratis. As (AS) inside ‘on behalf of the monarch’ (FOR THE KING).
7. Reverend – I wondered if rectors become reverends which would make this clue work very nicely. However it’s all a bit complicated – a rector has the right to the tithes of the church land, vicars and rectors are both priests which means they’re ordained. Reverend is a title for a vicar, reverend or priest. So reverend is simply a title which is the definition in this clue. The word play is (R)ectors, always (EVER), aim (END).
