Like I said, I might have misunderstood. From that it looked to me like Team Alpha is Takeyu, Koizumi and Asami. Then 'we' (the people in the Cargo Bay, or maybe just Team Alpha) will be joined by Murakami. When Misato says 'the rest of you' she is in a room with Takeyu, Koizumi and Asami, who she then names.
Everyone besides Mitsuko was in the Cargo Bay. You even said so in your posts.
"Misato stood stock still at the rear of the cargo bay."
"Misato pointed out the opened cargo do at the void and the planet below,"
The Cargo Bay is where the tank and truck are parked. It says so on the inventory page. The ship map also shows that. The Shuttle Bay is on the deck above and shuttles exit through a door there.
I'm working off the info I have and the posts I've seen. I have apparently misunderstood what you wanted, but it wasn't clear to me. So I had Mistuko act based on the information and situation as I understood it. If you need her to do something else, then just let her know.
