I agree with you on holding off on creating pages for now, but I'm fairly sure that the Female Squad Leader is the only one one of the four who could be named Marlene. I also think its very likely that the man sitting next to her is Klaus, as he can be seen in chapter 75 giving orders to Marlo's squad guarding the horses (and Erwin had just said in a previous panel that the squad guarding the horses was Squad Klaus).
