Yes, a voltage regulator can output a voltage that is too low if it is not properly selected for the application. Factors such as incorrect input voltage, component failure, or design flaws can lead to insufficient output voltage. Additionally, if the load requirements exceed the regulator's capacity, it may also result in a lower output voltage. It's important to ensure the regulator's specifications match the intended application to avoid such issues.
A regulator is referring to a regulator rectifier which converts the ac voltage put out by the stator to dc voltage and regulates it to a consistent voltage usually 12-14 volts dc.
The new alternator probably has a faulty voltage regulator.
Assuming you are measuring the voltage across the battery terminal, the variation is due to voltage put out by the alternator in combination with the regulation provided by a voltage regulator. The battery need a voltage higher than 12 Volts to charge. The variation you see would be due to the speed of the engine spinning the alternator slower or faster. The voltage does not go above 14.2 V due to the regulator

Assuming you are asking about the voltage regulator, the voltage regulator regulates the voltage being put out by the alternator or generator so not to overcharge or undercharge the battery and maintain the correct voltage for the electrical system. In 1964, the Lincoln voltage regulator was externally mounted. In later years it became integral with the alternator.
easy first to note this fan is 5 volts d.c if the battery is 12 volts use a low drop out voltage regulator at 5 volts out put you can get them from any electronics stores for around $3 or use 3 1.5 volt battery's in series that makes 4.5 volts like this (+ - + - + -)
Most vehicle manufacturers now put the regulator inside the alternator.
A 220 volt line may put out 250 volts because this specification features voltage that varies between 220 and 250 volts. In other countries, the electricity varies in voltage between 110-120 volts.
13.5 to 16 volts.
I don't know. Put some cardboard in it?
No
The voltage of 120 volts is more common that the lower voltage of 12 volts.
