Regarding today's update, there were no dead versions of Gamzee, Kurloz, Damara, Aranea, Aradia, or Vriska shown at all. And the main version of Meenah is the only one shown.

There are Aradia’s in there. As for Gamzee and Meenah, do to Gamzee not being able to die (Plot Armor) and Meenah having a really long lifespand, they both continue living in doomed sessions until the sessions fade out and cease to exist, that’s why there aren’t any of their ghosts around.  Kurloz and Damara are in service of Lord English and wouldn’t actively participate in a rally against him. And as for Aranea, she just sucks.
