Who are the people we don't have names for yet in the 6.2 artwork?

The eyes and red hair make clear to me the figure toward the bottom is also Lahabrea. The fact that he is merged with the center figure suggests the two are the same being somehow? Someone else pointed out that if Lahabrea is split between two beings, it would match Mateus from FF2, the original Pandaemoniums master. Might also explain why we seem to have conflicting character traits attributed to Lahabrea.
