I think number three ends in DON for Mafia boss. But none of the French words for cloth or rag seem to work. "Loque" was the one I knew without heading to Google Translate.
I did find "lambeau" meaning "shred, rag, tatter," but I guess Lamedon is a bit of a stretch from there.
I love the Ringbearer clue, and am awed by Galadriel's classical knowledge - I had to look that up before I found Thalia. (One could argue that you left Deagol and Celebrimbor out of the Ringbearer clue, but that would be to split hairs).
I'd suggest Cuthalion - but I can't justify it from the clue.
