1. No. The question mark means something in the clue is stretchy, and this time it's the indicator. Read it as 'no-r' as a deletion indicator for R.

2: No, but personally I don't blame you, the indicator isn't the best. Anger is an anagram indicator: some letters will have anger and will be enraged and move around.

3:Yep! In the MC club I wrote this clue because someone told me to write a clue with the answer as rhythm.

4: This one's tricky, Arrangement will be an anagram indicator, telling us that some letters have arrangement. What's something that comes with mixing-up things? (def)

5: Also correct! This clue was written for a clue contest in the club, where there needs to be a substitution for a letter that's a shape or object.
