When you go over a harsh speed bump or go downwards on a roller coaster, you experience this brief feeling of your internals going up as your body comes down. Do astronauts feel a similar sensation in 0G/micro-gravity environments because your internals are suspended relative to the rest of your body? Would I experience 0G (breifly) if I were to be stuck in an elevator if the cable snapped?

Yes. In the “normal” situation the gravity pushes your body against the ground (or against some structure that is pushed against the ground). It also pushes parts of your body against each other. The microgravity is what happens when you and everything around you is in free fall. This happens on orbit (orbiting is free falling), but also, for a brief time on a roller-coaster or similar device.
