There are no volts in a light. A light consumes power.
As many as you want. But where do you find 640 volts RMS?
6 volts
Onions don't have volts.

amps equals watts divided by volts.
Each light bulb will receive the full 9 volts from the battery in a series circuit, so each bulb will be operating on 9 volts.
It honestly depends on the type of flash light.
If a light bulb is rated at 60 Watts, the voltage will depend on the specific type of bulb. For a typical incandescent bulb, the voltage would be around 120 volts. However, for an LED or CFL bulb, the voltage could be different, such as 120 volts or 240 volts.
A fluorescent light bulb typically operates on a voltage range of 100-277 volts, depending on the specific model and design. The most common standard voltage for residential use in the United States is 120 volts.
.63 ampere draw @ 7 volts
The recommended voltage for 130-volt light bulbs is 130 volts.
