Wait, so when you switch on the parking lights(1 click up), the Main beams also come on....

Sounds like a problem with the LKM. The LKM is the biggest black box in the bottom of your first picture, it pulls out. MAybe one of the relays in your LKM is stuck on.
repairing the LKM here:

The horn problem is something else that I don't know, all I can say is check for power at the connector of the horn, which means removing stuff to get to the horn.

ALSO your #19 fuse slot looks burnt out.

ONE MORE THING. What Model Year is your 540i?
