Sorry - I thought this thread had died.
Well, in case anyone still cares,
Angrod and
Incanus are correct. (Squatter - "ancient mountain dweller" = Inca
n.)
"Corsair" is not correct for #1 - I think this clue violates classic cryptic clue rules, but it's a scramble, and "raider" is the straight clue.
#6 - a pun of sorts.
