I don't fully understand when exactly you become sure if you got the information correct or not? Because I filled out 8 people (other than the first 4) and I have no idea if it's correct or not

There must be something incorrect on some of them. It automatically progresses when you have three right. There is a tiny chance (I'd say about 0.01%, it's seriously very rare) that the game is bugged and not progressing due to some combination of cookies or adblocker, but in most cases it's because there's a mistake in some of the people you've filled in. If you're certain things are correct, I'd recommend coming to the discord and people can manually double check,
