Iron Man would beat captain America on a one on one, but captain America is the leader of the avengers so captain America would probably bring back up and beat iron man.
It seems pretty obvious to me that Captain America would easily win this match. Conan is an exceptionally strong, durable, and all-around fight-capable human. But Cap is superhuman. He's stronger, faster, way more durable, and quicker-thinking than a regular human. That combined with far superior hand-to-hand fighting capability (In the Marvel Encyclopedia Vol. 2, Cap is one of two characters in the entire book with a 7/7 combat ability rating, the other being Wolverine) would spell an easy win for Captain America.

I think thor because of his mjolnir
Thor would win in this fight, His hammer would easily pierce Juggernauts armour, not mentioning he can fly faster than the speed of light. Meaning he would knock Juggernaut out in one hit.
