Cockatoos in general are super dusty, much more than your tiels will be. I definitely recommend having an air purifier at hand, like everybody else has suggested above. It is fine to have 4 birds in your living room, yes. The key to having them in their safely would be to disease test any new birds you get in, at least for psittacosis anyway. As long as there is plenty of ventilation and room then go for it, if that's what you want. Just be wary of your other birds while s/he is out or if they're on top of his/her cage. Toes will be nipped!
