Those plastic boxes in the wall are generally right above where outlets or switches or wall mounted lamps would be. I am not sure if it is by law but usually wires in the wall are either horizontal or vertical a couple of centimeters under the ceiling. Those boxes are put where you either want to change direction or split off a line. In there will be a small coil of extra wire so if you ever need to redo connectors to switches etc and the ends are all messed up you can cut them off and gently pull out a couple of extra centimeters of wire.

The larger ones are usually openings to a chimney, typically found in older homes. Smoke ducts from a gas, oil or coal oven would be connected at such places to a chimney. The more frequent smaller ones are at connections of the electrical installation (funky blitzen boxes; Britzelbüchsen). Some may be used for installing a power supply socket, especially if they're near the floor or at half of the height of a wall - otherwise they're reallly just for threading power distribution cables and providing space for branching connections. Please mind - due to liability issues - that most work on electric installations needs to be done by trained professionals. For having no idea your guesses were pretty accurate.
It's a bit the old style, to save cables, they had accessible Y-Connectors behind those things. Today it's reduced, more cables are used from the fuse to the room, and Y-Connectors typically hide behind the outlet itself. On a newer wall with wallpaper over it, it's almost invisible.
It is a cover. Behind it are cables, so in case you would want to build a new power outlet, for example, you could take the cover off and don't have to open the entire wall to find a cable.

Your cables run high along the wall. Whenever there is an electrical outlet below, the cable has to branch off in such a little hidden box.

In US, you just take a hammer, make a hole in the wall, and search the cable ;-)
Well yes the first one is for exhaust but... i do not however know what the other ones are for.

Nice... a Daddy Longlegs at the end...
Bet they’re glad you moved there!!!!
