I have answers for 11A (Bravo, cool dude (6, 2 wds)) and 24A (Shut up a chimp in the house, say, with workout video (9, two wds)).
For 11A the answer seems to be a nickname for someone called Bravo, but I haven’t found a match.
For 24A the answer could be a new slang term for “workout video” but I’m struggling to parse it, particularly the second word. SH, APE are straightforward enough.
