they definitely would survive... half the stuff wouldn't even be an issue.
midnd rape (does nothing to Surfer and Hulk just walks through that kind of attack) - nil effect
8mi sq nuking (Hulk wasn't phased by a planet busting nuclear explosion, if anything it made him madder/stronger and as for Surfer ... lol, it might tickle ...) - nil effect
heat - really? nil effect
...
adding them together as a single attack, they still amount to the sum of their parts (as far as these characters go).
