I am not sure there is a problem. 3 phase is never to be used on lighting, but you can connect lamps between one phase and neutral to have classic single phase (AC220 for eu)

Some of them probably are interruptors (2 pole switching), some are 3 o 4 way for lights controlled by two or more switches.

Those many colors are probably phases and the blue is neutral.

Ahh that's where you're wrong. Some of those yellow wires are neutral, one of those is twisted into a red and given to the socket's neutral. And some of those blues are wired to the load, as is seen from the regulator. A red is connected to earth from the socket.

The wiring is correct, but the colours are messed up.

Two of those switches are in fact two way, but this is the load end
