The only one's that come to mind for me are other Chaos forces. Daemon Primarchs, Greater Daemons etc. although obviously they wouldn't be fighting Abaddon.
For other armies? I would say Vect could with a LOT of planning, trickery and diversion. Definitely not in hand to hand. Drazhar could probably make him sweat a little. Others above have mentioned others, Ghazgkull and Calgar might just, although I doubt it. I reckon Abaddon could pretty much take on anyone and win, the blessing of the Gods is not be taken lightly.
"Death? You want death? I'm afraid that would be far too boring."
