In the story I created, the Kingdom of Oneirou has 3 Moons--Artemis, Rahu, and Zorya--all of which have their own independent lunar cycles.
However, it's officially stated as early as Chapter 2 or 3 that, once a year [each], all 3 Moons' phases are synchronized to Full Moon and New Moon. Let's say, for the sake of argument, that all 3 (while operating on their own separate lunar cycles) still follow the same 30~ days to complete one full cycle.
If we pretend that Oneirou still has the same 365 days = 1 Year like Earth, is this possible? If both events are not possible within a 365 day period, then how long would their year have to be extended to account for this?

You can get orbital resonances like those exhibited by Ganymede, Europa and Io around Jupiter.
an orbital resonance occurs when orbiting bodies exert a regular, periodic gravitational influence on each other, usually because their orbital periods are related by a ratio of small integers.
However, that doesn't match what you are asking.
all 3 Moons' phases are synchronized to Full Moon and New Moon
when a conjunction happens, it's either Full Moon or New Moon or whatever phase it is, but it cannot be more than one in the same cycle. Moreover, for the Ganymede/Europa/Io system there is never a triple conjunction.
all 3 (while operating on their own separate lunar cycles) still follow the same 30~ days to complete one full cycle
if they have the same orbital period, they orbit at the same distance. So, either they are the same body, or they are going to become one very soon. As you see from the resonance, the periods are different.
To have more bodies sharing the same orbit, there must be one significantly more massive than the others, and the smaller one have to be in the lagrangian points of the large one. But then they won't have a simultaneous phase.

Could you have 3 moons equidistant around a planet, in the same orbit? I doubt it would fix anything, but it naively seems reasonable...

You say they all have the same 30 day cycle, but separate cycles? They must then have separate phases, like a 3-phase electric generator.
