Historically names like Muhammad Ali, Rocky Marciano and George Chuvalo are usually mentioned when heavyweights are discussed.
Light Heavyweights: James Toney and Michael Spinks tend to get mentioned along with Archie Moore.
Middleweights: Marvin Hagler and Jake LaMotta usually get mentioned.
Welterweights: Without of doubt Aaron Pryor makes the list with Julio Cesar Chavez Sr.
Light Weights: Roberto Duran and Sam Langford are the top two.
Little guys: Roberto Lopez and Khaisio Galaxy are the top two.
Active fighters, I give B Hop the nod, given his accomplishments it's hard not to acknowledge his chin.
Hagler, Toney, Foreman
George Chuvalo, Harry Greb, Jake LaMotta
Hagler Hopkins and Chavez Sr have the best chins I've seen.
Out of the fighters you mentioned, my top three would be...
1.) Ali
2.) Hagler
3.) Margarito
James Toney should be on that list. If he's never been KOed against top heavyweights ,he definately have a good chin fighting at middleweight some 20 years ago.

George Chuvalo, without question. He was never even knocked down in 93 pro fights, much less knocked out.
Hagler. That dude never went down, I think.
Duran
Hagler was never knocked down in his career, so I am going with him.
chavez, hagler and robinson come to mind among others
Ali, IMO.
