I believe being Sage of the Six Paths, has to include a mastery of senjutsu and or sage mode in some sort of way. Since Hagaromo knew the geezer toad sage and could also use the Truth Seeking Balls (made of 5 elements, yin yang release and senjutsu) along with the ten tails chakra which is really just a shit ton of natural energy it is safe to say that Hagaromo has some mastery over natural energy granting him a form of a sage status. We do not know whether Hamura was capable of using senjutsu in any sort of way so we can't really call him a sage. Of the sixth paths however both fall in the criteria because they both have six paths abilities.
