the first 2 pictures are a 240V breaker box.
The main breakers look like 100 amp service with 6. 20 amp circuits.
The third picture is a 110v single phase ancient POC.
If it's yours, you do not want to grow there.

The 4th is a phone terminal box.

Sorry fo' makin' you sad brah, but I calls 'em da way I sees 'em.
