There are so many literary devices in Macbeth that it would be almost impossible for us to go through all of them for somebody else's paper. There are many examples of irony (when the opposite of expected happens), metaphors (comparisons without using words such as like or as), personifications (when non-human entities are given human qualities), hyperboles (exaggerations), paradoxes (when two opposite things are combined), allusions (references to something outside of that particular play), alliterations (repetitions of the same consonant), assonances (repetitions of the same vowel), similes (comparisons using words such as like or as), etc.
