I think its a really good combo to take him on. Superman and Thor are Fast heavy hitters with other usefull powers. GL can use forcefields etc to protect, and lots of other usefull things...and of course the surfer with his energy manipulation.
yep, each of those guys could conceivably escape the pull of a black hole (if they haven't already, which i'm sure hal at the very least has), and yeah, with a very good showing they could drive him off...
Green Lantern creates a force field around calactus' head with superman and thor inside pummeling his face. Meanwhile the surfer keeps his body distracted.
Superman is nothing but a flea. All the solar energy he may potentially have will instantly be absorbed by Galactus. Baring that Galactus merely uses universal awareness, detects superman has a weakness to krptonite, and uses the power cosmic to form krptonite. Either that or supes is simply transmuted/turned to goo/vaporized/turned into a herald/etc. Silver Surfer can simply be stripped of the power cosmic and rendered useless.
Thor and GL give, at the extreme best, soft-mild resistance. The power ring gets transmuted/teleported away/absorbed/etc.
Galactus uses the power cosmic to isolate hammer from god and that's all she wrote.
The group has no chance in hell, unless Galactus is starving and
near-death, and even then it's noway near certain.

debateable...recall how thor with the avengers, the fantastic four, the starjammers, gladiator, an alien armada, and the silver surfer couldn't drive away a dieing galactus. they only won when they turned his own ship against him. recall...they were also losing...
