I'll try to explain it in few words.

Of cource, they were Otutsuki noblemen, also in the novellisation of the movie Kin was mentioned as a father-like figure (or even an actual father, I'm not sure) to Mo. If we consider them being alive since the Kaguya's era, their age exceeds a millenium (cause exactly a millenium passed between Juubi's sealing by Hagoromo/Hamura and the events of The Last movie). And yeah, if Kaguya had to create an army against them, it's likely she couldn't deal with them on her own. She was the first one eating Shinju's Chakra Fruit on the Earth, but since there are other planets with their own Shinju, and other Otsutsuki clan members dwelling in the universe in search of these powers, other Otsutsuki like Mo/Kin could gain chakra-like power at the same time or even before she did. Seems like Otsutsuki clan comes from another world and found a way to travel between them. We don't know the main goal of this, but Mo/Kin's goals are clear (assemble chakra to maintan eternal youth/immortality/power). No, they are not her descentands, they rather come from another branch of the clan which discovered the Earth after her.
