I've seen prior team/lobbymates show in the plaza after a match. I was told there's some way to order their clothes, even if I don't have the money to purchase them. What determines which teammates I'll see in the plaza and is there any way to cycle through NPCs to see player clothes from a previous match? Does it only show teammates from the last match or the one before it? If I reset the game, will I see additional past teammates or will it reset to no one? And how do I order their clothes?
You first need to talk to Spyke. He will unlock the ability to order gear from the people you see in the plaza. From what I understand, you see about 2-3 games worth of players in your plaza, so 15-23 (you don't count) unique ones to look at gear from.
Eventually, you will see "Order Gear" in the bottom right while looking at these players. The gear costs about 3x what it would in a shop. Spyke will order a maximum of one new item per day, and they are only held for one day. See here:
