Answer:
5:Yes. This is done many times in an electrical power system. Consider two AC generators supplying a power grid. In order to attach both generators three items are measured before they are connected. The voltages generated by each machine must be the same and the frequency must be the same. Last the phase angle difference must be zero.
Voltage - the voltage of the machines should be equal, that is, if one machine is generating 13 kV as its output then the second machine must also have 13 kV as its output voltage. If a generation with a higher voltage is connected to one with a lower voltage the higher voltage machine will force a current flow into the lower voltage machine.
