IDK much about these cars but do they have superchargers to compress the fuel/O2 mixture? How are these engines getting this HP?

Hellcat is a supercharged Hemi V8. It makes over 700 HP. The Demon is an upgraded version that pushes over 800 HP.

Not sure what Mustang and Camaro are doing.

I know some of the Lambos with 700+ HP are naturally aspirated (no turbo or superchargers).

The short answer is yes but modern turbos are generally considered superior to superchargers.

Anytime you want more than about 120hp per liter with road-going tractability you are going to have to pressurize the charge.

The benefit of superchargers is the fact they are powered off the crank they have no "lag" and the power is more or less instantaneous or at least closer to a naturally aspirated engine. They do make it hard to use intercoolers to cool the charge and have other packaging issues that turbos don't have.

Modern turbo systems have significantly reduced the turbo lag through a variety of means, are easier to package with intercoolers, and don't have the parasitic losses of superchargers since they use the exhaust gasses to power the compressor fan. They each have a characteristic aural signature but turbos tend to muffle the exhaust sound.
