I think all of them are of the same age. Mikan, Momo and Nana are 12 regardless of Momo and Nana lying for their age to attend highschool; Yami, for what I know, is also 12, however, stated in the 1st season that she is 24 in galactic calendar. For some reasons I think that galactic calendar years is 2 times the human calendar years. As for Mea, if she and Yami are created at the same year, then she is 12 as well. As for Yami being the older sister, it's common sense that whoever wakes up first after being born or created is the older one.

Please correct me if I'm wrong. I think I'm wrong.
