Well, who knows how many there were in reality, I'd guess much more (a couple of other balrog-like things, and there were also many of the weird creatures that are by some considered Maiar or somehow close to Maiar, like Goldberry, Gothmog the Lieutenant of Morgul and of course the ever-present Tom Bombadil. What I think about those is another topic, but I think it's correct to assume the number of Maiar in Middle-Earth did not end at 7).
