I think one of Mike's security guys is called "Archie", can't remember though

One of the 10 guys murdered in prison's last name is Boivin, can't recall his first

Walter White

Jesse Pinkman

Tomás Cantillo

The Two Rival Dealers

Jack McGann (one of the 10 prison guys, I think that's his name)

And last but not least…

Lyle

There's definitely heaps more, like Mike's security guys, but those were the ones I could list off the top of my head.

*Edit: damn, I just realised I named "Raymond Cruz" even though he's Tuco's actor*

Aye i didn't think someone would actually name Gus' empire members by memory. Thanks for trying

Holy shit
