It's been a while since I have watched MI, but I'll do my best trying to explain this.

It's unknown if these are the actual costumes or recreations in the mueseum. She could have the original, or  the one in the mueseum is the original, and she has a recreation. Either way, one of them is fake.

Now this one, I can't help you. I only know in-universe stuff, but I think that he could play any one of them, but mostly, random charcters like that end up uncredited, so probably one of them.
