I had the good fortune of seeing Randy Rhoads in concert before his death and I suppose he is the one that immediately comes to mind when I think about great guitar players. But really, many musicians have contributed to our enjoyment of their craft. I also like Joe Walsh, David Gilmour and Lindsey Buckingham.

This is all my opinion.

The only 2 guys out of the OP list that have any interest for me, are Ritchie Blackmore and Alex Lifeson.

The rest are pretty uninteresting for me. I no longer like any blues based music, and the list is made up of primarily blues based players. And I used to be fans of most of them.

My list of guitar heroes would look something like this, in no particular order:

Allan Holdsworth* - Gong, Bruford, Soft Machine, solo. Jazz-fusion.
John McLaughlin - Mahavishnu Orchestra. Jazz-fusion.
Steve Hackett - Genesis, solo. Prog
Robert Fripp - King Crimson. Prog, ambeint
Franco Mussida - Premiata Forneria Marconi (PFM). Prog
Alex Machacek. Jazz-Fusion
Steve Morse - Dixie Dregs, Deep Purple. Jazz-fusion, bluegrass
Daniel Gildenlow - Pain of Salvation. Prog-metal
Scott McGill - Handfarm, Mcgill/Manring/Stevens. Heavy jazz-fusion
Ralph Towner - Oregon, solo. Chamber-Jazz
Pat Martino - jazz/fusion, one of the best.
Paco De Lucia - could be the best Flamenco guitarist ever.
Sharon Isban - classical

*he is the guitar heroes' guitar hero.

Les Paul, Chet Atkins, Carlos Santana, Wes Montgomery (when he wasn't being pigeon-holed by the record company) Stevie Ray Vaughn, Neal Schon, and Mark Knopfler would be on my list, in no particular order.

Let's add Huey Thomasson...great guitarist for the Outlaws and Skynyrd.
