No you can not mix voltages. That being said if the lower voltage is part of the control circuit from a MCC control centre then yes they can be mixed as the low voltage control is part of the complete system.
Composite power & control Teck 90 cable has the power feeders and usually 3/#12 or 3/#14 wires embedded in the same cable. These three wires allow for remote stop - start controls to be mounted neat the motor out in the field.

Yes as long as the 120 volt control wires are insulated rated at 600 volts. The wiring also has to pertain to the control of the motor. For example a three wire stop - start station for remote operation of the motor can be run along side of the motor feeders. The motor feeders and control wires must all come out of the same MCC bucket. There is a composite cable on the market that is used for just this purpose. The cable has the three motor feeders and three #14 or #12 control wires and a ground all in the same cable sheath.

No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
Yes, 120 and 240 volts can be run in the same conduit.
no 208v is bigger
The conductors of any three phase circuit must be run in the same conduit. If the circuit requires a neutral, it must also run with the conductors in the same conduit. (If they were to be run in more than one conduit or raceway, the circuit would not operate properly.)
Back set for all conduit sizes is not the same. The greater the diameter of the conduit the length of back set increases. Without the diameter size of the conduit, an answer can not be given.
