If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
Voltage is a build up of electrons at one location relative to another location. To form a voltage gradient (difference), you need to somehow build up electrons at one location, or remove electrons from one location. Shuffling your feet on a thick carpet can do this!
The residual flux will help the phenomenon of changing flux. So that emf generation takes place.
It fails to build up because self excited DC motor's armature have only one direction of rotation. So that if the poles of the armature are reversed, then this causes the reduction in the residual magnetism and eventually, it will stop.
It's a diagram showing the components and connections needed to build a voltage stabilizer. The diagram will show a power transistor and a voltage reference, such as a zener diode.

List the factors that affect the voltage building in D.C generator.
If the object in insulated (or an insulator) , then that's what it does : build up until the voltage is great enough to jump the gap (to "ground").
yes
Anything that would allow the high-voltage to jump to the wrong place would certainly cause the engine to run poorly. Buildup around the outside of the cap would hold moisture which would allow the voltage to arc.
Stay with-in the amperage capability, the voltage capability, and use a heat sink to dissipate the heat build up.
Voltage-dependent-channels (these channels won't open until a critical electrical potential has build up)
What can usually happen is the permanent magnets in the generator will become energized, and like static shocks, will store energy in them.
