@mlunny1121: Yeah, under these conditions I think Alfred should be able to last an hour. Considering Cap doesn't even know how to access the Batcave, I'd say Alfred could hide out for as long as he damn well pleases lol.
Dick via superior stealth, tactics and gadgets. Takes them out 1 by 1. TMNT may take 2 or 3 rounds if they manage to make it a 4 v 1 (or MAYBE a 2 v 1 if the 2 are Leo and Raph). Otherwise Dick for majority.
