I don't agree with the underlined (or at least these are not examples of of what you are trying to say). "Up" indicates direction in all of them, i.e. all but c) can use "down to" and "over to" and the meaning would remain other than the direction of travel. c) cannot be over or down only be cause "climbing to the top" is up. In all of them, "up" can be removed without changing the meaning.Till / Until is temporal; the spatial equivalent is up to.
