Why does the car's electrical turn on when the brake pedal is depressed and the car is not running?
It turns the rear brake lights on as a safety feature. The brake pedal is pushed in, causing the fluid to move forward in the brake cylinder,activating a brake light switch. Even if the vehicle is off, the lights will still come on.
Why does the Third brake light blink when turn signal is in use?
You probably have a turn signal bulb with two filaments one for the turn signal and one for the brake light. If the ground connection is bad on the turn signal circuit then the current would need to find another path to ground. The only other one available is through the brake light filament to the ground on the center brake light. Try removing the taillight assemblies from the vehicle look for what is probably a black wire screwed to the body or a circuit connection and either tighten the screws a bit or clean the connections.

They are two separate circuits, each has their own fuse. The brake lights not working could be caused by a few things such as a blown fuse, blown bulbs, bad brake light switch, misadjusted brake light switch and depending on what vehicle you have, a bad signal light switch.

What does it mean when the rear brake light does not work and the turn signal flashes fast?
Usually when ones turn signal is blinking fast its telling you that a turn signal bulb (and in some cases a brake light bulb) is out. If it blinks fast when you turn on the the left signal the burnt out bulb is on that side of the vehicle (could be front or rear bulb so you'll have to check). And vice versa
