Q1 - Both plugs on a coil fire simultaneously - it's called the waste spark system.
Q2 - I'd expect the resistor is there to match resistance.
Q3 - Different lengths will have different resistance.
Q4 & 5 - You should measure the HT leads on their own.
Resistance checks are not final confirmation that a coil and HT leads are in order, as the insulation could be breaking down within the coil or between conductors and ground - to get some idea if the insulation is OK you need to test with a Meggar.
What plugs are you using and what gap?
Quality and not quantity counts.
