OK, here's my attempt, but now it's the last part of 4 I can't quite parse!
1. TRUNCHEON (club):anag. "turn" + he in "con"
2. DETENTE: tent in Dee (but not too happy about "cut off")
3. ARISTOTLE: "tot" & "l" in "arise"
4. TINTORETTO: TIN (can) + TORE (rent) + TTO (TT teetotal = rejecting the excessive, but can't account for the "o", unless "wholly" is intended as homophone for like a hole = O !)
