Yes, the amp rating is a measurement of the highest amp load it should carry. So a 15 amp appliance will work on a 20 amp socket but you wouldn't want to use a 20 amp appliance on a 15 amp socket.
Yes, providing the phase is the same. but you can't do the other way around, or breaker will immediately pop, or fuse will blow.
Yes, you can use lower amperage outlets - the problem would come if you were trying to run a 20 amp appliance on a 15 amp circuit or plug a 20 amp appliance into a 15 amp outlet. It would be better, though, as some kitchen appliances could exceed 15 amps (toaster ovens, some coffee makers, electric griddles, etc.) could try to draw more than the 15 amps your outlets are designed for. Perhaps you could get some 20 amp outlets and use those 15's in a hallway or something less likely to have high amperage draw.
It is not recommended. Light fixtures have a specific wattage rating for safety reasons and should not be overloaded. The internal wiring in a fixture is the bare minimum required to make the lamp light and is not rated for the higher wattage. The device that screws into the lampholder does not have a grounding point so the equipment that you plug into it will not be grounded. Wall recepticals have a rating of 15 amp and are designed to take the current. Use it instead.
It is recommended to use a slow-blow fuse with the appropriate amperage rating specified by the manufacturer of the fridge. Make sure to consult the owner's manual or contact the manufacturer for the correct fuse specifications to avoid damaging the appliance.
If the appliance is just to be plugged into a circuit with multiple outlets then you just need to make sure that the sum of currents for all devices on the circuit are less than the rated current. A rule of thumb is total current should be no greater than 80% of the rated current. So you might have a 20 A breaker and several 2.5 A appliances on this circuit. If you have a dedicated circuit for the appliance you would only need to size the breaker for the maximum current being drawn by the appliance. If the appliance contained a motor then there might be a start-up current that might be as high as 15 amps so you would likely go to a 20 amp breaker for a safety margin. As a practical matter a dedicated circuit for an appliance in the 2.5 amp range should have a 15 amp breaker. I always install a 20 amp breaker just for added margin and possible future applications.
If it is a 32-amp circuit you can use any appliance that takes less than 32 amps. That includes a 15-amp appliance. All appliances fed from that circuit must use 32 amps or less in total.

No it is not safe because it may be possible that the load 15 A may take grater than 15 amp and your socket and wiring may burn or damage.so i will say that use 20 amp socket it will safe for your device and also for your wiring connection.

Yes, you can use a 15 amp outlet on a 20 amp circuit. The outlet's amp rating should not exceed the circuit's amp rating.
No, as soon as you turn on the appliance the wire inside the fuse will melt as there will be too muck current flowing through it

The answer to this question is yes. The 30 volt adapter will supply twice the voltage required by the 15 amp appliance. The other thing is that 1 amp is equal to 1000 mA. Even if the voltages were the same, the output current of 1000 mA when 1100 mA is needed, is not enough to supply the appliance.

The total amps on the circuit exceeds 15 amps. It is possible your appliance is drawing more than 15 amps, but more likely that there are other things on the circuit causing the total current to be exceeded.
No, it is not safe to use a 15 amp plug on a 20 amp circuit as it can overload the circuit and potentially cause a fire hazard.
