 The Aristotelian all, some, no are monotone in both arguments (e.g. all is right increasing and left decreasing), as are at least five, no more than ten, infinitely many, whereas most, at least two-thirds of the are right increasing but neither increasing nor decreasing in the left argument. Exactly three, between two and seven are non-monotone, though both of these are conjunctions of a (right and left) increasing and a decreasing quantifier (e.g. at least three and at most three), in contrast with an even number of, which is not a (finite) Boolean combination of monotone quantifiers.
