input voltage is strictly according to applications. If use 12V dc adapter power 5V dc device, the 5v dc device would be damaged.

There may not be enough Power. I am checking this as well.

No, the voltage gap is too wide. The device may turn on but not operate in a manor that the manufacturer intended it to.

Can you run a 4.3v device with a 5v power adapter?

Yes, you can run a 4.3v device with a 5v power adapter as long as the amperage of the 4.3 volt device is under the amperage capacity of the 5 volt adapter.

Will a 5V 2.5A adapter damage a device that requires a 6V 2A adapter?

No, underpowering will not "power" the device, it will not run. You must get an adapter that is 6V and (2A or higher) will be ok as well.

Can you use replace 5V 3.6A ac adapter to 5V 2.6A ac adapter?

Well, trying to clarify your question, if you have a device that normally has a 5V 3.6A adapter, than it likely needs to be able to draw up to 3.6 amps or so for the device to operate normally. So, a 5V 2.6 amp adapter may operate at times, but only when the device is trying to draw less than 2.6 amps. If the device tries to draw more than 2.6 amps than you run the chance of burning out your transformer (the AC adapter), or just not having your device work. Both adapters will put out the 5 volts, but the 2.6 amp adapter will not provide enough current. You can safely use a larger adapter than the 3.6A, as your device will only draw as much current at 5 volts as it needs. On another note, do not try an adapter that puts out the same current but more voltage. Such as 7.5 volts 3.6 amps. This will overdrive your device and potentially burn it out.

Can you use adapter with output 5v 3amp to operate adevice with 5v 1amp?

Absolutely. The first rule: Source voltage should be equal to the device voltage. The second rule: Source current sould be higher than the cumulative of the device's current.
