(I say 4 due to having a 4 man dungeon immediately preceeding--though your three friends are mysteriously gone as well) You are definitely canonically solo against the HW final dungeon and boss.

EDIT: The lore does point out you're not the only one with Echo, but again, having a full party of eight in a lot of those instances...doesn't make a lot of sense.
The other Warriors of Light are referenced by Mimodi if you start in Uldah. She mentions the heroes that saved them previously (1.0 players). The Warriors of Light from 1.0 still exist and the cinematic at the beginning of 2.0 shows there are more than one.
The canon on this is not questionable. The game straight up says there is more than one Warrior of Light. Game trumps lore book.
