Hi Dillon. I think the second one is SHAREWARE (unlicenced computer programmes).
SHE containing A REWAR(D) (profit) reduced (having the last letter removed).
I can't help with any of the other ones. By the way, in the other post, I wasn't criticising you asking for explanations, I was criticising the poor clues in the Daily Mail crossword. Have you thought of trying the Daily Express - a much better crossword?
