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.
The voltage required for a light bulb typically depends on its design and intended use. Common household light bulbs operate at either 120 volts (in North America) or 230 volts (in many other parts of the world). However, some bulbs, like low-voltage or LED models, can function at lower voltages, such as 12 or 24 volts. Always check the specifications on the bulb for the correct voltage.
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.
