The output of a 12 volt transformer is an alternating current (AC). Your adapter is a 12 volt transformer but it has a built in half wave or, more expensive ones, a full wave bridge rectifier. What this rectifier does is change AC to DC. Bridge rectifiers are cheap to purchase. Connect it to the output of the 12 volt transformer and you will get a DC voltage. Great little project.
No, get a matching transformer and check the polarity and the milliamps.
What you will need is a 240 to 120 step down transformer. An adapter might work but it depends on what the current draw of the neon sign is at 120 volts.
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
It is generally safe to run a 4.3V device with a 5V power adapter, as the device should only draw the amount of voltage it is designed for. However, there is a slight risk of damaging the device if the voltage is consistently higher than the recommended level.
No and yes. A 120-volt plug-in timer connects the line voltage to the timer and to the switch that is operated by the timer, so you can't use it directly for a 12-volt light.However, if you use the timer to supply power to a step-down transformer, you can run a 12-volt light off the transformer (that's how most low-voltage landscape lighting timers work). If you don't need much current, you could even plug a 12-volt AC adapter "wall wart" into the timer. Otherwise, you would have to open the timer and modify it so that the micro switch is completely isolated from the 120-volt supply and bring it out to connectors for a 12-volt supply. Make sure you know what you're doing and also don't exceed the current capacity of the switch.

No. You should use the adapter specified for the DVD player. Using the wrong adapter can damage the DVD player and/or the adapter and/or cause a fire.

Yes you can - with a transformer. Maplin Electronics sell a converter that allows you to plug appliances that run on 110V into the normal UK mains. See the related.
There are many electronics today that run on 12 volt DC power. The good news for anyone who is traveling is that you can use a 12 volt AC adapter 12 VAC 2A.
Use a transformer.
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
No! You would damage it beyond repair.

Yes, but you are limited to the amount of current draw the 120 volt load can apply to the adapter.
