They would all get absolutely battered by any world class boxer.
This is Anderson's boxing record

lol at Conor having "done it already" too. He got clowned and played with by a retired 40 year old Floyd, who made a name for himself at 130 pounds. Conor would get absolutely demolished by any good prime boxer around his weight at 154 or 160.
Here is how he looked in a boxing ring, against an elite fighter.
Adesanya has done better than most. He holds a win over Brian Minto, who is a known name at least. Even that sounds better than it really is. It's the same Brian Minto who got beaten up and stopped by every decent fighter he ever fought, and Izzy could only manage a SD over a 40 year old Minto.
Out of the names you suggested, Max, Poirier and Yan would do the best. Mainly Max because of sheer durability, workrate, stamina, and chin. For those reasons alone he'd put up somewhat of a fight and not look quite as silly as the rest of them, against an elite boxer.
