what would be the right way to ask this:

[kazike]

who do you live with?
or
Who lives with you?
or
who is living with you?

thanks in advance

 

[bhaisahab]

who do you live with?
or
Who lives with you?
or
who is living with you?

thanks in advance

They are all correct, it might depend on context.

Well, if you want to be a purist, and a pain in the you know where, then the first sentence should be "With whom do you live?"

However, I suppose I might as well give up and say it the other way.
