The latter three (~さん・様・先生) aren’t really pronouns, though. Sensei can technically function as such when we already know which one is being discussed, but you would never use the other two on their own. These are titles/honorifics.

彼・彼女 are pronounce. We also have others こいつ・あいつ・and basically whateverqualifier人 (あの人・その人).
