Where are the motor mounts

Located on a 1993 accord lx. Front, rear, and are there any others?

I think there's 4.
 
Front, towards the radiator.
Rear, under the firewall.
Front of engine, near drive belts.
Tranny, maybe blocked by battery?
 

This pic might help you, the rear subframe mount is different if 5spd or Auto.
 
The most common motor mount problem for your year is the front subframe mount/to the trans,#15; the rubber at the top of that "dogbone" cracks out.
If you have an Auto trans #4 mount it is vacum actuated and there is also a little linkage on the back side that sometimes comes loose
