Tornadoes nearly always spin counterclockwise in the northern hemisphere and clockwise in the Southern Hemisphere with the exception of about 1% which are called anticyclonic tornadoes.
Yes. A tornado will generally move in the same direction as its parent storm.
That varies. If you are close enough to be in the area of the tornado's inflow then the wind will blow almost directly towards the tornado, perhaps a little to the right of that direction. In that case the wind direction will depend on where the tornado is relative to you. If you are beyond the inflow area for the tornado, then nothing about the wind direction would indicate the approaching tornado.
The speed and direction of a tornado can be determined using Doppler radar by measuring how far the tornado moves between sweeps and in what direction.
THAT Depends on where the Storm that produced that Tornado is going
spine is reference direction and spline is curve, but in GSD spine is curve passing through plane.
A tornado that spins the opposite direction from normal in its hemisphere is called an anticyclonic tornado.
run at an oblique angle to vertical direction of the spine.
Tornadoes change direction all the time. All that happens is the tornado goes somewhere other than where it was originally headed. It is impossible for a humans to change a tornado's direction.

It came out of the west.
No. A "sand tornado" (which is a dust devil, not an actual tornado) will move in whatever direction the wind around it is blowing.
A tornado can move in any direction, but most move generally east or northeast.
