Mr. Krabs would be retired and old, but still loving money.
Spongebob would be at least the owner of The Krusty Krab, and married (not sure if married to Sandy though O_o) He would still being that happy-go-lucky little sponge that we all love, but on a bit more mature way.
Squidward would be a still famous clarinet player, or a famous painter.
Patrick would be as stupid as always, with the exception that he'll be married and have little starfishies! lol
Plankton would have given up on the patty formula and make it as a famous actor playing Man Ray! lol
Sandy would be about to move away from Bikini Bottom (her contract is suppose to expire in 20 years, unless the chimps re-new it)
Gary will have little snails with Snellie, and they would all live with Spongebob and Sandy and their mutant sponge-squirrel kids on the pinapple that would be a bigger pineapple of course.
