I’m a bit faceblind so this might be a stupid question: Is the same character speaking in every frame? Which is which? I’m confuse

In case anyone else is confused: 180 degree rule

Fire Department Chronicles on YouTube has some really funny skits, but the complete lack of respect for the 180 degree rule or any sort of consistent blocking/sightlines can be really distracting: watching this, I have no idea where each of these characters are standing relative to each other.
