No, there are no such things as "hid lights".

Yes, HID lights need a ballast.
HID lights measure brightness in lumens, which is a unit of measurement that quantifies the total amount of visible light emitted. The brightness of HID lights can also be influenced by factors such as color temperature and beam pattern. Automotive HID lights are commonly rated in terms of lumens output to indicate their brightness level.
Yes.
Depends, HID KITS are not legal anywhere in the US, they violate US DOT law. HID lights that come factory with a proper projector designed with HID in mind (higher end cars; Audi, Mercedes). Practically, if you aim the HID lights down, as to not blind other drivers, its unlikely that a cop will pull you over, as they can't really tell if your lights stock or an addon kit.
Aftermarket HID's are illegal in ANY state. Period.
There is definitely a way to make your HID lights brighter. To make your HID lights brighter, you can purchase and install xenon projectors or specifically designed reflectors. You also have the choice of upgrading your reflectors to halogen headlamps to make them even brighter.
