How to control ESC from Arduino?
There are quite a few issues I see with your setup.
You are setting up the ESC in your code to use pin 9, but your diagram shows that you've connected to pin 8. Pin 8 won't do anything because the ...

What exactly are PPM controlled ESCs? Are most ESCs available to build quadcopters PPM Controlled?
I believe there is confusion about these terms. Strictly speaking, the ESC is PWM controlled. Although the signal usually gets there from a transmitter and receiver signal that is PPM encoded.
It ...

Electronic Speed Controller
It depends on the voltage.
Say you are running 12V:
1820W / 12V = 151A
With a 24V system:
1820W / 24 = 75A

What exactly are PPM controlled ESCs? Are most ESCs available to build quadcopters PPM Controlled?
I'm not an expert re: PPM communications but, from what I can tell, PPM signals contain pulses which are interpreted by the receiving microprocessor (or speed controller) as position commands. If the ...

What happens when I connected my unpowered servo connector power wire to the powered arduino 5V pin?
Should be fine. If I remember correctly, the inputs to the ESC (more or less) control power mosfets. Putting input to a mosfet without power does not hurt it.
