Many examples can easily be found in or around Cyrano's "nose" speech--when he is insulting Valvert's lack of wit, then fighting a duel with him. I'll give you one example of each; you can certainly find more on your own.
Metaphor - "'Tis a rock--a crag--a cape--...a peninsula!"
Simile - "I do not dress up like a popinjay!"
Irony - "But I have no gloves! A pity too!" (verbal irony--he so wishes he had some gloves!)
Hyperbole - "When it blows, the typhoon howls....When it bleeds, the Red Sea!"
