It really depends on the size of the tank and the disposition of the fish. Although PBTs are usually considered one of the more aggressive tangs, there are people who claim their PBTs are puppy dogs or even skittish fish. If you have him now....what is his attitude like? That will help determine his demeanor in the future.
If you're going to something BIGGER than the 120 you have listed on your profile, then you'll be in pretty good shape with most of the other tangs as long as you've provided a good combination of hiding holes and swimming room. From what I've read, I'm not sure it's a good idea to put a Naso in anything less than 240....preferably an 8 foot tank, but at least 240g. The Yellow or Sailfin should be good mates in something larger than 120, but you'll probably want to add the PBT last.
