1. No, Leviathan are stronger than any type of angel, and easily. They're sooo strong, that they're called the 'supermen of monsters.' To put it into perspective for you, Dick or Edgar could pretty easily each take out Gabriel and Raphael at the same time on their own. Every single time someone's gone up to a Leviathan and "won," they always had help. For example, in Survival of the Fittest, Dean needed Cas to kill Dick, and Cas needed Dean there too. Or in Slash Fiction, Dean, Sam and sheriff Osborne all needed each other to take down the Leviathan. In Shut Up, Dr. Phil, Dean and Sam needed Don to paralyze Chet to stop him from massacring them. In the Purgatory scenes, Dean and Cas needed each other to take down Leviathan.

2. So far, angels have never teleported in the presence of Leviathan, that's just not true.
