So, decided to go through the images and for those that like lore and not really understanding whether something means something or just looks cool, I noticed that there may be at least 2 more moons than those 3 Nodoka talked about and that false moon that Makoto mentioned (maybe).
Noriko seems to have a Pink Moon (Dark/Hot Pink?):
As implied by the pink light that tends to be around her, especially at night, but actually shown in the 'She Is' Chapter 3 Main Event, during Noriko's date dorm war with Futaba. (2nd Dorm Wars)
Then there's how Ayane apparently seems to have a Dark Moon:
As shown during her 'Nevermind' Chapter 2 Event, which took place around the 3rd Reset (slumber party with Molly and Tsuneyo), and happens to be the one that mentions the Word of The Day; Perception, and tries to tell us about the Third god, before USER2 talks to us. Ayane was also briefly surrounded by green and blue light:
Before the green light seemed replaced by a Dark Moon. It happens to be the time she somehow got to the roof without a key at night, and is the reset she made it to the roof, only to vanish and lose the baby.
Later on in Chapter 2's 'Alderaan' Main Event, this Moon seems to show up again, with Blue light nearby. (2nd Beach Trip, and after Molly gets jealous over Otoha with Rin)
