It is certainly unsafe.
No, you cannot plug a DC 12V device directly into a 220V AC outlet. Doing so would likely damage the device and pose a safety hazard, as the voltage and current specifications are incompatible. Instead, you should use an appropriate power supply or transformer that converts 220V AC to 12V DC for safe operation.
No. the plug configuration is different, just for that reason so that the two voltages can not be crossed over.
No, it is not safe to plug a device rated for 125V into a 220V outlet. This could result in damage to the device or a potential safety hazard, such as a fire or electrical shock. It is important to match the voltage requirements of the device with the voltage supplied by the outlet.
Only if it's a 220v system.
No, you cannot plug a device rated for 125V into a 220V outlet directly. Doing so may damage the device and pose a safety hazard. You would need a voltage converter or transformer to safely use the device with the higher voltage.

A 9V DC (direct current) supply can be either positive or negative, depending on how it is configured. Typically, in most applications, a 9V DC source is positive, meaning the positive terminal has a higher voltage relative to the negative terminal. However, if the terminals are reversed, it can be considered a negative 9V DC. The designation of positive or negative is determined by the polarity of the voltage applied.
A: No problem but don't expect the power to increase
Yes, no problem.

No. 9 v is only 75% of 12 v.
No. Usually it's a -/+ 10% difference. So, a 9v would need at least 7.2 volts or more
No.
No. Attempting to run an appliance on insufficient voltage can cause damage to the appliance and can be dangerous. Call an electrician and get him to install a 220v plug
That's almost twice the voltage. The chances of frying your device is high.
In Digital multimeter we use 9V Dc battery.
