I am level 32 ice and my friend just beat big ben, but is a higher level. Is it possible to beat big ben by teleporting
You can, but I don't recommend it. Do you even have the quest? If not, it won't count. Big Ben is a good dungeon to try to solo (with planning). I just did it today with my Storm wizard, and have done so with Ice (Death, Life and Balance) as well.
