Eternal champion=The Eternal Champion's fate is left unknown at the end of Arena, however it is thought that they may have returned to their home province hailed as a great hero. Uriel Septim also claims that the hero will rule by his side, so the Eternal Champion may had been given some form of power over the empire after the events of the game.( in the manual he is named Talin and the general of Uriel is also named General Talin Warhaft)

Hero of daggerfall= dead (In one of the Dragon Break's continuities, the Hero was killed in Aetherius, effectively destroying the Hero's soul for eternity.)

Nerevarine= Indoril Nerevar Soul(godkiller,Nerevar the captain,Nerevar moon-and-star.) It is unkown what happened to him but there are rumors that he travelled to akavir and stayed there, we also know that the nerevarine might still be alive because of Corprus( stops aging and 100% immune to illness) so maybe during the 4th era could be anywhere in mundus.

Hero of Kvatch = Sheogorath (everyone know what happened in shivering isles,in skyrim shegorath himself mentioned that he know martin septim become a dragon and the only person with martin during that time is the hero of kvatch) we know that daedra dont die they respawn in their own realm when defeated.

The dragonborn= a dragon soul in the body of a mortal. meaning he is once a dragon before his soul was ressurected, his soul is immortal but his body is mortal.

Meaning all of them are different persons and different souls..
