If two group of people meet each other and someone says:
You are losers!
Will it be correct if he will be answered like
Who are losers!? We? Naaah, you are!
Or it should be said like a singular form
Who is loser!? We? Naaah, you are! ?

You wouldn't call the group of people a loser, you would say that the members of the group are losers, so you must use are.
It sounds very formal to use we? when you can use us?, and this is probably not a formal situation.
For these reasons, you should say:
Who are [the] losers? Us? Nah, you are [the losers]!
Hope this helps!
