that's the council of Widsdom, not the council of Elders.
They predate the Council of Elders.
Going by your list:
-He-Ro is not part of the Council, if you notice, he's standing behind Eldor.
-The Faceless One was part of th council, but he's banned in this issue.
-The Star Child (in our story many Star Child existed)
-A Female Gar member (no name)
-An old Gar member (no name)
-Lord Bryon of one of the old houses of Eternia. Their flag is the Swan and can be seen on the Eternia Central Tower toy.
-Mather Tetsudo, an old turtle-like female.
-A fire people member (they can be seen in a Filmation episode) (no name)
-And you're missing the Alien council member, same race of the aline Cosmic Enforcer sculpted by the Four Horsemen and then discarded in favor of a more human Zodac.
