Just one padlock is enough, but you can use up to 6.
You need all the locks removed before it’ll open, so you don’t need to count on someone to carefully count everyone back in. You just make sure that each person uses their own lock

I think it’s so you can create “and” conditions for unlocking. IE: If you’ve got two locks, each with their own key, both person 1 AND person 2 need to unlock it. So you can have multiple people and/or multiple crews working on the machine across different aspects. Maybe one crew is doing electric, the other some kind of plumbing, and they’re working at different times. When one crew finishes their work, they can release their lockout without making it unsafe for the other crew.

Exactly this. Everyone working on that machine slaps their lock on it, and every last lock needs to be removed before the tag can come off. The welders might finish in half a day, but the electrical or water or hydraulic guys might need a whole weekend to get done, so this makes sure someone doesn’t say “oh the lock is gone” and make mincemeat out of some dude’s head.
