No, it adds or subtracts from the font's "native" line-height, which is
equivalent to its size.

If by vertical size you mean "unaltered line height" - yes. Widths are
glyph-specific. If the actual width of an M is 1em, it's an accident.

Not sure what you mean by "line-height grouped in". In a 12-point font, the
actual distance from the top of the ascenders to the bottom of the
descenders is typically a bit less than 12-point, in order to keep these
from touching on contiguous lines when set without extra line height
