Yes, but only if you had first learned that the person had at least a few. For example, he may have said something like "I come from a large family" and you reply with "Oh really? How many brothers and sisters do you have."
Even if they were all boys, that sounds more natural to me.
However, I agree with "Do you have any..." that I would use the "or" version.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
