From what I can gather, at least with the first 3 clues (spoilers for people who want to solve it themselves):
The first clue is “a puff of smoke” if the admirer’s a smoker, or “a cloudless air” if they don’t smoke.
The second clue says they’re “dancing” if they’re one of the four people dancing, or “standing” if they don’t dance.
The third clue deals with whether they drink white or “finest red” wine.
I believe this narrows it down to two suspects, and getting the other 3 clues can help you identify which one’s correct.
