"Then" is only an adjective when referring to a past position or occupation, and ideally should be a hyphenated form (e.g. The then-chairman of the board).
It is usually an adverb (it happened then), but can also be a noun (that was then, this is now; until then) or a conjunction (e.g. the price rose then fell).
No, it is a verb or a noun (to go around, to surround; a round shape). The adjective form is circular.
