Answer: They are just people trapped in the further after their terrible death. It would be nice to later find out the back story on them in a future film.
Answer: It's implied that the girl went crazy and killed her family, but it's not really elaborated on. They're just some of the many spirits to be trapped in and haunt the Further, likely due to the violent nature of their deaths.
