Yes one person can physically operate a car lift as it works simply on hydraulics. However it is essential to have a second person present in the preparation for using a lift to guide the car onto the lift ramps successfully and for safety's sake having a second person present while you are working under the ramp. But in essence it is physically possible to operate a lift with one person, just not advisable.
