Yes.
Not only that, Gandalf the Grey fought a Balrog for 7 days straight, the Balrog’s individually could probably solo hundreds of Nazgul before dying.
The Nazgul are really only dangerous because they’re immortal, combat wise they are quite weak. Sauron’s armies were nothing compared to Morgoth’s lol, Morgoth had Balrog’s and great Drakes while Sauron had lesser Drakes and trolls, lol
