The usage in Answer 4 is metaphorical and idiomatic, but 'face' is still a noun there; 'face value' in Answer 1 refers to the taking of things by appearances (e.g. a banknote with a 'face value' of £10 may be a forgery; a smart person with a smile may in fact turn out to be sad, or an assassin, or both). 'Face' here is either an adjective (meaning 'on the surface; as seen; by denotation rather than connotation') or perhaps an appositive noun (as in 'face cream'); but certainly not a verb.
