It has been well established in the manga that Ashura and Indra transmigrated throughout the generations. But personally, I don't think that they were the only two out of the Otsutsuki family to transmigrate from generation to generation.
Yes, I know Hagoromo didn't transmigrate, but what if he is just an exception? What if his mother, brother and father (if he has one) transmigrated as well?
My theory: All of Hagoromo's family tansmigrated except for him, Hinata is Kaguya's reincarnation and as for the other two, I don't know who they could be the reincarnations of.
