Yes, the 2 Hz will not make any difference at all. As the frequency gets lower the motor will run slower but you will never see 2 Hz in speed reduction.
No, the voltage of 500 volts is too high to operate a 380 volt motor.
no
What effect will be there on the motor (Induction) output power when a 100kW 50hz motor is connected to a 60hz power supply.
Yes. It will make your motor a little faster though, so it depends on what you are powering with this motor. IE Can the piece of eguipment be ran faster?

One way would be to hook it up to a supply (by itself, with no load) and measure the speed with a contact tachometer. If your supply is 60Hz, and the motor speed corresponded to one of the standard motor speeds, it would be a pretty safe bet you had a 60Hz motor. If the speed was about 20% faster than a standard speed, the motor is probably a 50Hz motor. Or 20% slower if you were running a 60Hz motor on 50Hz For instance, a 1750 RPM 50Hz motor would spin at about 2100 RPM if you ran it on 60Hz.

Depends on the current rating which should be on the motor.
Yes, however, the RPM will increase by 20%, if the motor is connected to a shaft or driving something that can not handle the torque, then you might run to heating issues or performance issues.
Yes, but it may generate more harmonics
You need a 5.5kw generator to run a 5.5kw motor.
The fan will physically get warmer and the blade speed will increase.
Not really because motors are designed to run at either 50 or 60 Hz and the wrong frequency might cause them to malfunction or overheat.
