I believe this mural in the Brightmoon Council Chambers shows the founding members of the previous Princess Alliance.  

The first panel has (I’m guessing) the Princess of Snow, Frostra’s mom, and some nature Princess, maybe Perfuma’s mom.  

 The man in the turban I’m guessing is the Prince of the Seas, Mermista’s dad, based on clothing and his icon looks like water drops.  The other man in the panel has a flower icon and might also be Perfuma’s predecessor.  I have no idea who the woman there could be.

The center panel shows Queen Angella and King Micah

The fourth has Castaspella, though I don’t know if she has an official “Princess” title.  The figures below her are Netossa and Spinerella.

I have no idea who any of the figures in the last panel could be.  They all seem to have a star theme though.  The star headdress on the middle princess could also be a stylized version of Catra’s headdress.  One of the holograms in Light Hope’s vision also had a cat tail, suggesting their could be some cat kingdom out there.
