When power is off, how many degrees of rotation is the shaft able to rotate?

If you have no power to the motor there is no rotation. You will break the gears if you try to force rotation.

Hola buenas tardes. Queria saber cual es la ventaja de elegir "regalo" al momento de comprar?

Normalmente no envían la factura del artículo para que quien lo reciba no vea el precio, o burles los impuestos a pagar cuando llegue a tu país

are these motors ok for frequent starts and stops ?

It all depends on load...if you are worried you could ramp your starts and stops.

where can I find a 3d Drawing for this part to load into a cad program

I made my own from dimensions I found on internet. And - they are cheap enough to just buy one and measure it.

OK but some slack in gear train.
