It has to be pointed out that due to the Nerevarines connection to Azura, and with the Nine being essentially imperial Deities, and the daedric princes attempts to manipulate the protaginists, aswell as the likelyhood that they all engaged in one 'immoral' acts or another it's highly unlikely that any of the heroes are avatars for the Nine.

It's possible they're all the same person, since the Nerevarine becomes immortal, and Dunmer have long lives anyway (assuming Nerevar is incarnated as a Dunmer) however that would mean that the Dovahkiin meet him/herself as Sheogorath. In Oblivion, if you do the Shivering Isles questline then go to Sheagorath's shrine to do his Daedric quest, Haskill says how sad it is you've taken to worshipping yourself.
