None of those are machines. Those are likely all free-weights. I only say "likely" for the bench press, as it could be a machine, but is unlikely. People that do squats and deadlifts tend not to do their bench press on a machine.

Squat could also be with a machine (smith machine), but it's unlikely for someone doing deadlifts.

eww, but yeah, forgot about that one (probably purposely).
