What is discrimination factor of electrical circuit protection?
Electrical discrimination is to do with selecting the correct protection in the fault path of an electrical circuit. To illustrate, if you have a machine at the end of an electircal circuit and that is protected by a 13A fuse lets say, and then you have a 20A circuit breaker protecting that at the consumer unit (fuse board), and then the main switch on the consumer unit is a 10A circuit breaker, then every time the machine uses more than 10A of power the main switch will trip and disconnect everything connected to it, that is where discrimination is not achieved. Basically it is where the circuit protection closest to the macine is smaller and it gets bigger as it goes boack to the source, then discimination is achieved. I hope that helps. If not then it probably need a drawing to help answer.
What is the difference of a Circuit Breaker from an Air Circuit breaker?
They are completely different. A moulded-case circuit breaker is a low- or medium-voltage device, whereas an air circuit breaker is a very large circuit breaker designed for use in high-voltage transmission/distribution substations.

Is An open in the main line of a parallel circuit causes all individual branch currents to be zero?
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
