The amps it draws depends on how big it is. Typically 2-12 amps. Check for a manufacturer's plate that shows the wattage Most of the load in a rice cooker is a resistive heating element, so the amperage will be quite close to the wattage divided by the voltage (220 here).

Amp draw is always combined. 220V is uncertain if it is three phase or not, because there are both one phase and three phase applications of the 220V motor. In any case, the answer is always "combined".

a 2p 20 amp should work fine for a single 220 air conditioner,
Only if it's a 220v system.
A 30 amp breaker is designed to trip at an earlier point than a larger 40 amp breaker so one appliance that operates on lower amperage level could be unsafe or damaged before it could trip the higher 40 amp breaker. Also, the existing wiring may not be rated for 40 amp service.
No, it is less current than .0001.

No, a 30 amp shore power plug is strictly 120volts. A 50 amp shore power plug is technically a 220v system, however the camper uses the two 120v wires in the cord separately. There are no 220v appliances in RV's today.
Identify the neutral wire on the generator. This will be the unused conductor to run the compressor. The ground and line1, line 2 are all that are needed.
85 amp/h you can only use about 60% of that so thats 51 amp/h. 1000w 220v uses 4.6 amps so take 51/4.6 and u can run for about 10 hours
You can't. A 220 volt dryer requires 220 volts in order to operate properly. It will not run on 110 volts.
