Sure, here's the revised paragraph with different names for the buildings:

The A-1 class of the first years resides in a building called "Aurora Hall", named after the stunning natural light display that can be seen in the polar regions of the planet. It's the building where famous individuals belong, as well as other students that were recognized by the Stella Academy, who deserved to be granted "Player Scholarships". And Luna was one of those students.

Then, the A-2 to A-7 classes of the first year reside in a building called "Orion Tower", named after the constellation that can be seen in the night sky.

While the A-8 to A-12 classes of the first years reside in the "Sirius Hall", named after the brightest star in the Earth's night sky. It's the building where Luna's older brother was stationed.

The other dormitory buildings were called the "Phoenix Tower", for the A-1 class of second years. It's named after the mythical bird that is said to be reborn from its ashes. Then, there's the "Centaurus Hall" for the A-2 to A-7 classes, which was named after the constellation that depicts a centaur, a mythical creature that is half-human and half-horse.

After that, there's the "Hydra Tower" for the A-8 to A-12 classes of the second year. It's named after the many-headed serpent of Greek mythology.

When it comes to the third-year dormitory buildings, there exists the "Gauntlet Hall" for the A-1 class of third years, named after the armored glove worn as a symbol of challenge or defiance. Then, for A-2 to A-7 classes of the third years, it's called "Nebula Tower", named after the interstellar cloud of dust and gas.
