Sorry, don't know half of them.
Girthwise, I haven't seen a white guy in mainstream porn like Shorty (you didn't list him). Perhaps if you look outside mainstream porn, then there's guys like Stretcher.
Shane I would compare to Ramon. Ramon probably a tiny tad longer, Shane a tad thicker. (Then there's of course the "one drop" argument, but I think that's only if you're American). They are close to being cock twins

Not sure if Big George was up there, but think he passed away, so not important.
Jack probably belongs here as well. Almost as thick but a little longer than both. Lothar (White pony) would probably settle well against Jack as well.
Julio and Vlad could possibly be compared - they come across somewhat similar in both before and after sizes. Not sure if Dredd should be mentioned here as well - he changed size as well - although I'm not sure on his before size.
Lengthwise it's probably Mandingo and Danny D. Of course with Mandingo as the winner. Not sure what the difference is - 0.25" or so?
