Can you restart the engines after the fire extinguish handles are pulled?

  If just pulled, on most types you can push them back in and that would reconnect hydraulics and generators etc. A restart should be possible. If you push and then twist to discharge the fire bottles I'm not sure you can restart, given that the discharge could cause damage.

  Sure, if you have enough altitude after you start the APU and reset the engines. The extinguishers contain halon or something equivalent, which will be cleared out when you spin up the engine. But I doubt there's a procedure for it. If you have enough altitude to restart, you have enough altitude for an emergency landing. It's better to follow the checklist and land on a runway with no engines, where emergency equipment is available. Rather than getting creative and crashing in a field because you failed to restart them.

    It's much safer to land with engines running than dead stick. The crew is going to try to get the engines running if at all possible.

    > It's better to follow the checklist Indeed it is. The checklist will have you attempt a restart.

    Landing a jet without engines means landing a jet without hydraulics, which is difficult. The emergency power from the Ram Air Turbine (drops from under the plane when engines fail to maintain some hydraulic pressure) runs out when the plane is about to land/crash as its airspeed is relatively low- then the hydraulics are barely working and you don’t have “power steering” anymore. In past incidents, pilots plot a course for a glide landing, and then work to get the engines started.
