As has been stated, it depends entirely on how long the fight goes on. Thor could easily one man all of them at the beginning. His hammer is crazy powerful when fully unleashed, even in the MCU. It kills multiple leviathans in avengers, destroys an ice fortress in thor, level a city in thor, and was powerful enough that thor thought he had a reasonable chance of destroying the aether in dark world. He could easily fry everyone, including the world engine.
That won't happen though. Not his style. The longer the battle goes, the more likely the kryptonians get strong enough to overwhelm the avengers. Hulk would absolutely be able to take em out at first before eventually being contained, though probably not killed. Iron Man is pretty durable, he was able to tank being tossed around a turbine with moderate damage. IM3 showed heat is a major weakness though. However, the kryptonians don't know that, and it seems like a pretty advanced technique. He'd get pried out of the armor eventually. Repulsor blasts can deliver similar blows to what the kryptonians can dish out, at least for awhile, so he'll at least be able to tango for awhile. He's also much more mobile with experienced flight.
Cap and the others have to play support on this one. Maybe they could disable the world engine from within. They're not taking out any enemy combatants though.
Overall, I'd give the avengers the edge but not by much. I'm thinking 55/45 avengers. They throw hulk into the evemy ship and it's toast. Thor would last a long, long time, and probably fry up some kryptonians steaks. Hulk is slower but once he grabs a limb, it's smash tine. Ultimately, I don't think the kryptonians have enough numbers to get the job done. The avengers start out with the edge and since time is a factor, they're more likely to win, but just barely. If Zod's numbers were higher, they'd last long enough to crush em.
