It may work if the base is the same but it would only be half as bright.
The light bulb should still have the same limit - 100 watts, because the limit is set practically by how much heat they produce. You need to make sure the wiring in the chandelier is correctly insulated for the higher voltage.
25w
If the lamp bases are the same for a 220 volt bulb and a 110 volt bulb, then yes. If any modification to the pendent lamp have to be done then no, as field modifications to electrical equipment will null and void the certification that the manufacturer had to obtain to be able to sell the device.
The voltage must be adapted to whatever is the standard voltage in your city: either something close to 110V, or something close to 220V.
If all the components are rated to 220V, yes. Keep in mind that if the appliance was designed for 110V it may arc if 220 is run through it. If you don't know the device can handle 220V, don't run it at 220V. Chances are it was manufactured cleaply and cannot handle the extra voltage.

If you can use it in your lamp it will be a 20 watt bulb

Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
Yes, you'd have to change the plug or use an adapter, and also change the bulb. Thry make the standard "medium base" A19 bulbs in 220v also. here's a few: http://www.bulbs.com/Light_Bulbs/Medium_(E26)/200V+-/results.aspx
Power is calculated from volts time amps. 110V x 0.727A is 79.97 watts. Note that power is not "consumed" but rather converted to other forms of energy such as light and heat.
No
If the bulb's voltage rating is OK it will glow normally, If the mains voltage is 110V and the bulb is a 220v European one it will glow at half brilliance. If it is a 110V bulb and is taken to Europe it will burn out immediately
Not usually, the most common reason for a light bulb to fail is vibration. The very hot filament is very vulnerable and if tapped or shook could easily break. Most bulbs have one support in the middle of the filament. Rough service bulbs have up to three filaments supports but these types of bulbs cost more to purchase.
