This question already has an answer here:
If I'm not mistaken, a total of 14 Valar, not including Melkor, are named in The Silmarillion. Are these the only Valar, or are there others who are not named/mentioned?
Bonus question: As I understand it, all the Ainur were either Valar or Maiar, and any Ainur who isn't a Vala is a Maia, and vice versa (the special case of Melkor notwithstanding). Is this correct?
