It's possible, with Rizevim's existence I always considered there may be other Asmodeus, Leviathans, Beelzebulbs and Lucifers around. They just don't care or are indifferent to how things have changed.

Shalba, Katarea and Creuserey were all likely angry at not getting the title of Satans because they were the most likely to be named heirs to those titles, and Vali was an exception due to Rizevim's abuse and being a hybrid.
