You may be able to pull it off given the cars you're talking about, but my hunch says no. You'll need to take exact measurements and get measurements of the equipment you plan to buy.
Generally, about 10' minimum is required. My ceiling is 10'-5" and I have a Bendpak 4 post lift with two cars.
Like others have stated, you need about 4"-6" to raise the lift off the safety points, then you have the thickness of the lift itself, a buffer at the top so you don't crush the roof of the car, possibly the garage door itself.
I didn't have to worry about the garage door, because it doesn't go over the roof of the car, but the trunk and some of the rear window. The shorter your ceiling height is, the further the garage door will go into the garage as it hugs the ceiling and then may become a factor to worry about. If you have a super deep garage, you'll have to have the lift towards the front to avoid this issue.
Overall, there is a lot to consider. I spent hours researching, thinking and measuring before I felt confident it would work and placed the order.
One thing I forgot to consider was the increments of which the safety resting points occur. It just so happen to work out for me ok (I have two safety points to choose from), but I kicked myself for overlooking/not thinking of it ahead of time.
For you, given your standard ceiling height of 9'-3", this could make or break you as it seems you're only going to have one safety resting point to choose from. Too low and you'll be on top of the car below, too high and you'll crush the roof of the car as you raise it to take it off the safety resting position.
