if you're only a mile from home, start in first gear - in other words put the car in first, then crank it up - it will lurch forward and start - then drive slowly home without shifting.
if you have to stop along the way, put on the brakes and don't be alarmed as the car lurches to a stop.
if the car is in another gear now and you have trouble going to neutral, you can try rocking the car (get out and push it a little, let it rebound, push again) then try the gears shift again.

Sure, why not?? How much of your driving time is spent using the clutch?
To go forward, WHEN YOU ARE READY to got, put it in first, start the engine
and drive away. If you have to back out first, start it in reverse.
Snatch it into neutral before stopping and shutting the engine off.
Minimize the necessity for stops and carefully synchronize speeds to shift.
A little practice before this happens to you is worth its weight in gold.

Start it in gear; standard procedure.
Shift using the throttle.

My clutch cable broke in the garage one time and I couldn't get the thing in gear til I had a new cable. Unless maybe someone got under the car and pushed the fork arm while you put it in gear.
