Yes, this used to be done for a few reasons but is not seen much today due to power electronics taking over the applications.
Uses were to change frequency, supply variable speed dc (Ward Leonard), override voltage dips (with flywheel).

one very common application is in high power broadcast transmitters. these transmitters require 3 phase power for the HV rectifiers and blower motors. however in remote mountain top locations the rural power is often only available as single phase. the single phase powers a motor which turns a 3 phase generator. About 20 percent of the input is wasted as heat, but at least the transmitter operates as specified by the manufacturer. in the trade these are called "rotary converters".

Yes you can, only the power the moter uses would be more than the generator can produce. Most motors run at 1750 R.P.Ms. The generator needs to turn 3,600 R.P.Ms. A 2 to 1 gear box would have to be used.

Yes you can but you lost energy by doing that. If you just want to convert the electrical power to a different voltage or electrical output, there are more efficient ways to do that.

The only reason to use a generator is to furnish electrical power where none exists.
If there is no electricity available, how would you run the electric motor???
If electricity is available to run the electric motor, why do you need a generator???

of course, it is done all the time...of course don't even think perpetual motion machine!!!
