"oh really? I thought the sister's is under sccubus ancestor's command since she bore the sisters (,right?)"

I haven't heard anything about any connection between them and the Succubus Ancestor (well, besides said Ancestor being their Ancestor).

It's just that at one point in history, there were three extremely powerful succubi sisters, and after they died, their names caught on (Hence, there's more than one "Lilith" and such - they were famous succubi, and new succubi were named after them). It's not entirely clear if these three are the original Succubi Sisters coming through Tartarus from an alternate past, or if these are new Succubi named after the original Succubi Sisters. (By "Not Clear", I mean "Luka and companions wonder about that, but given the way the game is set up, they're probably the original three sisters")

"Nevertheless, the sister is still on Fateburn Family's side... unless Alice 15th has gone rogue (which is unlikely) or they are accidentally serving the imposter you were talking about without knowning it."

They themselves identify as working for "Alice the 15th", which would be Alice's mother. If you're with Alice, they're even surprised Alice the 16th ("our" Alice) was left out of her mother's plans - they expected her to know about what Alice the 15th was planning. That being said, chances are that Alice the 15th is either the original, who came back from Tartarus with new allies, or an alternate version of her brought in by the White Rabbit.

"I don't know, I'm still waiting for the translation patch. :P"

Won't help you. The details aren't explained in Part 1. You'll have to wait for Part 2. And the translation of Part 2.
