Honesty is more than telling the truth, it means having integrity. The pilgrim who shows these traits the most is the Knight. The Knight "followed chivalry/Truth, honor, generousness, and courtesy"(Lines 45-46). He does great things for his kingdom and the people in it. He even remains humble in spite of those achievements.
Similarly to the Knight, the Parson is a respectable person. "He [is] an honest worker, good and true/Living in peace and perfect charity"(Lines 142-143). The Parson helps anyone he can for free despite living in poverty himself. He could take advantage of his position like many others have, but he chooses to remain among the people.
While the Knight and the Parson are examples of honesty, the Monk is the opposite.
