In physics (at high school level, at least) vectors are quantities with both a magnitude and a direction in space. For example:ForceDisplacementVelocityAccelerationElectric fieldMagnetic fieldGravitational fieldAt a more advanced level, physics makes use of vector spaces other than the familiar 3D space we seem to inhabit. In relativity, for example, a 4-dimensional vector is used to describe energy/momentum, and another to describe the scalar/vector potentials in electromagnetism (there are many others too). In quantum theory, complex vector spaces (Hilbert spaces) are used to describe the space of states for a physical system.
Fahrenheit, Celsius, and Kelvin
The resultant of two vectors cannot be a scalar quantity.
speed and direction
Meters Miles per hour
Units that are used for measures in which the direction is relevant. Example are displacement, velocity, acceleration, force.
Meters per second squared, Kilometers per hour, Meters, and Miles per hour.
yes
A vector quantity can be described in many different units, because there are many different vector quantities. For example, a distance - when the direction is relevant - would be indicated in meters or km. (plus a direction), a velocity in meters per second plus a direction, an acceleration in meters per second square, plus a direction. Electric field might be indicated in Volts / meter, if I remember correctly again, including an indicating the direction.
It is neither a scalar or a vector? Scalar and vectors are used to describe quantities, for example scalars include distance and mass, while vectors include weight and velocity. We do not say that a situation is a scalar or a vector.

No. The same quantities in different units.

Scalar and vector quantities are used in mathematical models of phenomena. Accurate modeling allows people to understand these phenomena. People are helped by better understanding of the world around them.
It depends on the type of product used. A dot or scalar product of two vectors will result in a scalar. A cross or vector product of two vectors will result in a vector.
