Haki is a mysterious power that’s observed in every existing form in the world. It’s not that unique from the common senses. Still, most people don’t notice it or fail to wake it. There are two kinds of Haki accessible to everyone, given the usual training; though, there’s a third kind, that just a special group of “chosen ones” are supposed to hold.

Luffy seems to have also learned Busoshoku Haki to an extremely great level, which has been exposed to darken any part of his body and harden it.
Usopp has aroused his Kenbunshoku/Observation Haki while the last half of the Dressrosa riot, as he was able to detect auras of Law, Luffy, and Sugar, who were in the royal palace. With this, he was capable of pinpointing Sugar’s position and shooting her down from a range.
Usopp hasn’t still had control over it, as he just awakened it, while he attempted to beat Sugar.
Jinbe is the 10th member of the Mugiwara Pirates, and he joined them the Whole Cake Island.
