It has mainly two questions, Q1 and Q2. Further, please correct any detail which you deem to be grossly wrong. And please your reply simple. Thank you for your help.
If you were using a device which was clocked at 1Hz, that would indeed be two 1's. Otherwise not. Correct terminology is "duty cycle", which is measured in a percentage rather than units. For example your top waveform is 50% duty cycle.
