[A Christmas Carol] what exactly are the ghosts of Christmas exactly?

They are called “Ghosts” but either then Jacob Marley they don’t seem to be dead humans.

There is a Ghost of Christmas Present every year before rapidly dying.

So are the other two eternal? What is their purpose why did they send Scrooge on a look throughout his life? Are they Faerie beings? Angels?

They seem to be manifestations of their respective concepts, so they're spirits, but more in the vein of an elemental spirit.

Althrough you could totally read the Ghost of Christmas Future as just straight up the Grim Reaper given how he only shows Scrooge Death.
