Many has it or has the qualifications for it but if they awake it is another matter.
Jinbe, Nami , Usopp, Vivi. To be honest maybe all of the strawhats.
Dragon, Sabo, Kuma, Iva, Bunny , Law, Fujitora
Koby, Momo , Sai , Cavendish
Garling, Shamrock, Beckmann, Mihawk, Crocodile, Buggy, Blackbeard
Akainu, Aokiji
Maybe many more someone like Chinjao has it after all.
We know it is genetic.
Doffy for example has it from one of his parents even though they are weak.
Sanj has it most likely from his mother
But if you follow what Rayleigh said: those who made names for themselves have mostly CoC.
So you can assume the majority of Schichibukai has it or at least you can assume at least they have the qualifications for it.
Those with known epithets most likely are kings.
Sabo the flame emperor
Kuma Tyrant
Iva the Okama king or Miracle worker
Koby the hero
Etc.
I think it just every CoC user manifested his haki about something.
Garp wants to protect the marine Koby maybe the same.
Dragon about change and protection of the common people.
Kuma about the protection of his daughter
Luffy about freedom
Zoro about the sword
Sanji about love
Shanks about friendship
Akainu about his absolute justice
Hancook about her beauty
