There is no telling. Look for an hour rating on the packaging, but you can really never know because of the environmental conditions that may affect the life.
You can as long as the rating of the inverter supports the 1500 watt power requirement at the operational voltage of the bulb. There may be a surge at start-up of the bulb so that has to be taken into account.
They will last about the same period of time.

yes the bulb will actually last longer
If you mean the 40 watt light bulb inside, are you sure you are replacing it with a special 40W appliance bulb? A regular bulb will not last long at all inside of a refrigerator.
This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used.

If it is a 40 Watt bulb it converts energy at the rate of 40 Watts as long as it is switched on.
No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.
Watts is Watts and has no relation to time. w=v*a (west Virginia varsity). A 60 watt light bulb is 60 watts regardless of how long it is on. Watt hours would be what PG&E bills you for.
Any replacement bulb, LED or not, can be used, so long as the voltage specs are respected and that the bulb's contacts are of the same type.
Yes.
A watt is a measurement of electricity, usually pertaining to light. Light bulbs luminosity is graded by wattage, such as a 60 watt bulb, 100 watt bulb and so on. You would find a watt in a light bulb, to start.
