Sounds like TN-C-S. There’s a gazillion tradeoffs between those things, above my paygrade, and TBH above the paygrade of many many many electricians unless they happen to be network techs.
Hi, so should I just grounded the neutral wire from the fuse box (the one that goes from the pole into the house) instead of running a ground wire to each devices?
Your neutral should be bonded to ground anyway. If you have current on the neutral that needs the ground path, something is wrong.
That really depends on the network. The only connection between PE and N might be at the power station (TN-S) or there might be no wire at all (TT).
All the house I wired had neutral bonded to ground wire at the panel.

The best practice is a separate ground wire. But there’s plenty of houses without them.
