Well, they do all look alike.
I do believe there were rumors of Obi Wan (who we know is a real individual) seen at the same time as one going by the name Qui Gon Jinn.
Although I have reliable sources that claim the male human going by “Obi Wan” at the time was not bearded while Qui Gon was. Obi Wan could have been actively using a decoy as his ally Amidalla was known to do.
There was another later going by the name Luke Skywalker, but again it could have been Obi Wan. There were no reliable reports of Skywalker’s whereabouts at the time, and the real Skywalker had no beard when last seen.
