In the 3 demensiones we use, some use time as a forth, yes. Even traveling trough a wormhole will make you move even though you end up a place that is farther then what you have actually moved the distance you have moved is still positive.
True
yes
The measured value is always positive from one point to another when it represents a distance, as distance cannot be negative. This is because distance is typically defined as the scalar quantity that expresses how much space is between two points, irrespective of direction. In contrast, other measurements like displacement can be positive or negative depending on the reference point and direction.
the distance between two points is length
The distance between identical points on a wave is called wavelength.
The distance between any two different points is always a positive quantity.

True
Measurement always deals with a distance of a line or a distance between to objects, distance between 2 points, and so on.
True
True
The shortest distance between two points is always a straight line.
Not necessarily. The distance between (0.0) and (0.5, 0.5) = 0.7071 (approx).
