17D wordplay is 4-letter 'party', with an abbreviation for number inside It's a misprint..
32D wordplay is the name of a star (4-letters) {in the constellation Cetus} with a single letter 'unknown' inside. It's a jumble.
Re 20A, definition is first word. Wordplay is 5-letter "winds" reversed with a 3-letter dialect word for "box" inside. If you have all the crossers, then the first four should give you a good idea what winds we're talking about.
Thanks jbird at #45.
Got 32d quickly from your hint. (Tough one!)
But not 17d, after hours of thinking. Can't see the party, with the crossers I have. I think I need to put an F into the definition but no idea how. Don't have 16a either.

17D Party is a verb, Aussie slang. The misprint impacts 'six'.
16A First word is definition. 3-letter 'ridicule' inside 5-letter 'series of notes' shortened.
