I am not a Subject Matter Expert but will try to help;
You have to be a bit more specific. What country, what year, what block are you inquiring about?
Yes, on the F-16 that do carry drag chutes for landing, it is typically mounted at the base of the vertical stabilizer.
Depends which version and year. Some had the chute removed to accommodate equipment, some removed equipment to accommodate the chute. Others moved the equipment around to have both.
Which versions? what is the aircraft weight? weapons configuration? weather conditions? etc.
There is no "zone 5", at least I never heard anyone call it that. I heard min AB or max AB. Fuel flow is not set in stone, depend in altitude speed, weather, specific engine, etc.
