As the question seems to indicate that characters named must be either false or fair, perhaps naming those who are both false and fair can first be done in order to eliminate them.
CHARACTERS WHO ARE BOTH FALSE AND FAIR
When Macbeth remarks, "So foul and fair a day I have not seen," this rhetorical device, chiasmus, in which the order of words in one clause is inverted in the other, becomes a motif of Shakespeare's Macbeth. Macbeth and his wife Lady Macbeth move from being brave, fair, loyal, and loving people to rapacious and murderous characters. So, for the largest part of the drama, they are false as they conspire to attain the heights in their kingdom. In a despicable crime, one against the Elizabethan Chain of Being as well as the heart of man, Macbeth murders his own cousin, the good King Duncan because his "vaulting ambition" drives him to the acquisition of power. Of course, his wife has catapulted him into this act with her having "unsexed" herself and threatened his manhood.
Another character who plays both roles of fair and foul is Malcolm, the son of King Duncan. However, he plays foul only to test the loyalties of Macduff, who comes to England. Malcolm is naturally suspicious that Macduff may be an agent of the treacherous Macbeth and questions him as to why he left Scotland when his wife and children are now unprotected. Feigning cupidity and lust for women, Malcolm describes a villain. When Macduff utters a cry of despair for Scotland, Malcolm is satisfied that Macduff's intentions are honorable and pledges to fight for the crown and kill the evil Macbeth.
