You don't say where you live, how can I assess your area humidity
today ??

Yes it will shoot one spark in a dry atmosphere.
Depending on the design of the unit,
it could make you sit down or lower !!!

How far - Under what conditions - Why? - do you aim to kill or disable people or just create a BIG lightning show


There is a good reason why the BIG shows come from Tessla coils not VDG's or Whimhurst machines.

Again -- see the Boston Museum Of Science's website. Their "theater of electricity" runs Van De Graff's own generator (originally used as an atom-smashing accelerator) and Tesla coils. The former puts out bigger single sparks, the latter put out more sparks. (The big Tesla coils also throw more amperage, and so are probably more dangerous.)

Florida is a great place for Fulgurites, I would be searching sandy areas
as soon as a storm moved off.
Lightning energy in sand melts the sand to glass.

Yes, if the weather is dry and the target object is well-earthed.

In perfect conditions, I've had sparks up to six inches long from my school's clonky old VdG with a worn band.

Yes if you give it a good ground such as the ground or a metal sheet underneath it.
