It is unknown if Rachel's story can be about Five's origin, but I'd say it's about the Origin, since the story features "a book", Master Unit, most likely, which the girl tried to "finish" with her memories.

Five may be based on the Origin, but nothing was said to prove this statement right or wrong.

Some people believe that Five was based on Terumi Saya, which I think is unlikely, since how could she possibly be devoured by her brother? Naoto is a normal human about to turn vampire, not a potential Black Beast or a Grimoire owner.
