One circuit should be fine for all 3 contactors assuming the coil voltage is the same. One thing you need to know is if the contractors are electrically held or mechanically held. Some mechanically held lighting contractor require to control wires. One to tell the contactor to open and one to tell it to close. Often these must be momentary inputs to the contactor, but some contactors have "clearing" contacts that permit the use of maintained inputs.

Yes the coil voltage is the same and its electrically held

The lightning contactors , electrically held, 120v coil, 4 pole, 20 amp contacts, Nema 1 enclosure and one of them is a 12 pole contactor
We are supposed to hook up the timeclock with the 3 contactors and a 2 hr override timer switch

How is this supposed to function? Time clock on/off, override to change the status of the time clock?
