What are the four boxes in the picture below for? The fat pipe to the left goes up to the electricity meter. I've also included pictures of the two labels I could find.
Also, why is there a green plastic rope coming out of the first box? I found the box slightly gaping with the bottom screw missing1, and the rubber water seal around the cover a bit ripped where the rope is coming from. When I pull on the rope, there seems to be no resistance as if I could completely pull it out of the box. The fact that the seal is cut up where the rope is makes me think it wasn't supposed to be there in the first place…Should I pull out the rope and fix the seal of the box's cover?
1 I placed a new screw as seen in the picture, so that the box isn't gaping wide open (to rain, insects, etc.)…

That is non metallic (PVC) electrical conduit.
There must be wires in them that come from or go to the inside of the house to an out building or ?? .
The green cord could be left there for fishing ( pulling ) new wire from one of the ends. Have you seen this green cord near any other electrical fixtures?
The covers come off to facilitate fishing the wires, It can be difficult to fish the wires thru many bends, so with this setup, you can pull a length of wire from one direction thru the open body and then pull the remainder as you help feed in to the body to complete the turn, then put the cover back on.
