Having said that, Dormammu stalemated Odin in Asgard. So that's how I see that fight going down.
Thor "beat" Umar once, but she was faking it. Who knows how it would go down if she really wanted to win. I'm going with Thor on this one.
Satannish is said be second only to Mephisto in power (but this is debatable since on panel whenever they fought it's been inconclusive) so how does this translate into a Bor vs Satannish fight? I don't know enough of Bor to say.
Hellstrom vs Loki, I'll admit I know very little about Hellstrom but I'm going with Loki.
So Team God wins.

Umar was above newbie strange but she was far below him as sorcerer supreme. I think i'd put her a bit above Thor's level, but it is a difficult fight. Her power varies as well, sometimes she is above Dormammu and sometimes she is below him.
Satannish and Dormammu are both skyfather level, if not greater. I think overall the demons win but it is a tough fight.
That was the stalemate. They were fighting but to Thor's mind it appeared as if they were playing a game of chess because his mind couldn't comprehend what it was witnessing.

Didn't Umar have something to do with that?
Dormammu was operating on behalf of Lord Chaos and Odin, Master Order. She really was trying to throw the game in favor of Dormammu.
