I decided that this is as far as I wanted to go with this image, considering that this is a reference pic for someone else's use.
EDIT: A new ring persona was added after this pic was drawn.

From left to right:
Gran Terremoto (Great Earthquake)
Agua Toxico (Toxic Water)
Fuego del Noche (Night Fire)
Espiritu Prismatico (Prismatic Spirit)
Cielo Apocaliptico (Apocalyptic Sky)

Not pictured:
