Uh. No. The RWBY universe has one moon. How broken that moon appears is dependant on the phases of the moon; Monty explained this to us ages ago. Rather than appearing as a crescent like our moon, the moon rotates and we see the broken sides. So when the moon is full, the undamaged side is facing towards us. When the moon is broken, it is because the moon has rotated and the damaged side is facing towards us.

There is only one moon on Remnant.
