That is a Chassis GND, it can often be connected to Earth or may form part of an AM loop antenna.
Ground (electricity) - Wikipedia, the free encyclopedia

And antenna is well an antenna tuned for AM reception. Can be as simple as a length of wire.

That is external AM antenna port if needed. Not for FM.

External antenna unit may have two terminal for connecting to a receiver. One is signal output and other is ground.

That screw(with caution) looks like a fix for FM/or SW telescopic areal. If you unscrew it you need to open the cover to fix it properly.
