Well done Andy! They have exactly the same sound (according to Chambers pronunciation guide) but a different meaning, A homonym.
Here is my working. Hope satisfactory. I'll only be around for a few minutes as "she who must be obeyed" has a task for me.
1. homonym (get = hear) of “shakes” = SHEIKHS = girl’s ideal film heroes (OLD sl) {Chambers def}; hence the “old” girl’s...
2. (cryptic) YOU NAME IT
3. tax (paid) = impost; as an alternative to = or; IMPOSTOR (Chambers)
4. subtractive anagram (out & drunken) of “disorderly” – “dry” = SOLDIER = fighter
5. a short prayer (RC) = act (Chambers); friend’s performance = anag of “friend” = infred; yielding, infr(act)ed = INFRACTED (adj) = interrupted (Chambers)
