Blake and Sun sort of snuck in, so it isn't surprising that no one noticed them at first. It wasn't until Roman looked over and saw the two that he did see who they were and attacked. I'm also not sure what you meant about Neo. The first time she appears (in combat) she uses her umbrella to block Yang's attack. Then when Yang goes to punch her out, she lowers her umbrella at the last second only to reveal she wasn't even there anymore and was on an airship. Either way no matter who attacked her at that point, she would have been fine as she wasn't even there to begin with.
