When Jesus returns, will there be different groups of people still alive, at that moment of the second advent?

Won't there be one particular group, the remnant of Israel, who will believe on Jesus as their Messiah?

Will there also be Gentiles still alive, who had believed on Jesus during the Tribulation?

Will there be any that took the mark of the beast, yet still alive at the moment of the second advent?

Will there be people who hadn't yet believed on Jesus, but for whatever reason, had not taken the mark of the beast, and are still alive at the moment of the second advent?

Will there be any survivors of that great earthquake, yet trapped under the rubble?

Will there be people still alive in torture chambers and dungeons, suddenly free from their torments?

Will there possibly be people still in submarines, or underwater domes, that will be brought back up?

Will there possibly be people still on the space station, or on the moon, or even on Mars, or transit or in orbit, that will be brought back down?
