1. I believe it's actually a period of time your demotion immunity lasts for, not a set number of games. We don't know the exact time because we're not given an notification about when it expires.

2. Your rank is completely reset when a new Season arrives. However, your MMR is only soft-reset, or brought closer to the average MMR, at the same time. If you do average in placements your rank will typically be at around the same it was before.

3. Who knows?
