Companions in Pillars of Eternity 2: Deadfire are covered on this page. Companions can join your party and aid you in combat. Upon recruitment you can choose a class or multiclass for a companion from the list of possible options. WARNING: this choice is permanent and cannot be reconsidered lately in the game. Some companions have their own unique subclass, abilities or equipment.
Also each companion has their own personality, temperament, preferences and personal quest. While being in your party companions will react on words you say to them or other NPCs and decisions you make. Each companion has a set of character traits - beliefs or demeanors they approve or disapprove. Drawing on this set they will develop relationships with you and other party members, and some of the relationships can even end with romance.
Unlike companions, Sidekicks do not have their own personal quest, have very limited conversations and do not participate in party relationship system. Information on them is covered here.

how do I heal the wounded crewmember
Btw, Vatnir is a Sidekick, not a Companion.
That drunk Orlan in Fort Dreadlight is a side kick. Merkle or something...
You overlooked Rekke.
There is another companion not listed here (or SIDEKICK as the game calls them) called Fassina. You can find her in "The Dark Cupboard" which in turn you can find in "Periki's Overlook" in Neketaka. After you complete the quest she gives you, you can ask her if she would like to join you.
I found another companion- Konstanten in Neketaka. Dwarf Chanter/Barbarian
I found another companion far to the east, lost in the sea. I will add information as soon as possible
