If x and y are horizontal, z is vertical; if x and z are horizontal, y is vertical. The words horizontal and vertical are generally used in a planar (2-dimensional) sense, not spatial (3-dimensional). Which is the reason you may not find a word corresponding to the third dimension along with horizontal and vertical.

If I want to speak of North, South, East, West in a general sense I could, for example, use the term cardinal direction. Which term is appropriate to sum up horizontal and vertical in the same man...

2 'Horizontal' means 'relating to the horizon', so strictly speaking whether a split is vertical or horizontal depends on its orientation relative to the ground. Or less strictly, 'horizontal' is whatever the observer considers to be left/right rather than up/down.

Orthogonal does not imply horizontal and vertical movement. Orthogonal implies that one movement is at a right angle with respect to the other. Horizontal and diagonal movements are thus always orthogonal, but two diagonal movements can also be orthogonal to each other. In fact, the two diagonal movements in chess are orthogonal to each other.

The convention is that x would occupy the horizontal axis, while y occupies the vertical axis, regardless if x is plotted against y, or y against x. Visually, which often would appear mutually indiscriminatable for 1-1 mapping plots.
