For me, it depends on the game.
I can play Beat Saber or PokerStars VR for hours and not care.
Assetto Corsa or MS Flight Simulator? As soon as the car/plane starts moving, I get queasy. I can only handle a single lap around the Nurburgring before I have to take a 30 minute break to let my stomach recover. In MS Flight Simulator, I gotta stick to large aircraft that maneuver very slowly and have massive cockpits.
I'm fairly sure my experience is pretty common, which is why I always feel people are doing a MASSIVE disservice to VR adoption when they let someone try VR for the first time and it's a racing game or a roller coaster simulator.

When I had an HTC Vive, it felt heavy on my face. When I updated to an Index, it was a world of difference. The strap design on the Index does a much better job of putting the weight of the headset on the top of your head, spread over the strap.
I don't know about any of Meta's headsets.
All of the above. Often games will have "reduced motion sickness" settings that sacrifice some realism.
Different people are affected to varying degrees by VR-motion-sickness. Personally, I'm not at all: I can spend hours in VR and not mind at all. Others are sick in moments.
