Spider-Man would probably lose this fight since Ironman has a lot of utilities and guns not to mention his body armor.
If you think about it there really isn't any thing that Spider-man could do to him.
Ironman would certainly win this but as Tony looks to Peter as a son I don't think tony would go all out on this fight.

Carnage is the winner hands down. Venom thinks he is a defender of the weak and Carnage does not care about human life. I see carnage using a hostage to get the upper hand. Carnage is stronger, faster, and his symbiote has more powers. Carnage can create bladed weapons and throw them, he can extend tendrils from any part of his body to grab and attack, and venom's spider sense does not work him.
It would be a long fight, but in the end, clayface would win. He can shapeshift, and sandman can't, so clayface could catch him off guard and suck him up with a vacuum.
