At each Time Heist point, they created a new branch in the timeline. They then returned each stone to the Time Heist points, thus erasing those splinters of timeline, leaving only the main, normal timeline. It wasn't main 2014 Thanos that was killed, it was Splinter 2014. He left Splinter 2014 and was killed, then Splinter 2014 was cut off. Nothing changed with main 2014.

The stones were destroyed by Thanos in 2018.

Loki's still dead. They didn't change the overall timeline. As for the Loki that escaped, that was in Splinter 2012, which then got erased by replacing the Mind Stone.

Because he knows the time and date he left when he was younger, so he knows the time and date to go to that bench.
