These two characters are not similar whatsoever. Eurymachus is a deceitful person, always scheming, thinking of plans how to enjoy himself and doesn't care about others. He even wanted to kill Odysseus' son Telemachus. He treats everyone with disrespect and is extremely arrogant. These are not adjectives that describe Odysseus, even though he did show arrogance when defeating the Cyclops.
The order in which the characters die in Act V, scene 3, would be Paris, Romeo, then Juliet, so option 3.
