The prince's first two lines are a use of amplification as he is repeating himself for emphasis. This makes the story more dramatic.
Benvolio uses epithet when he is mentioning that Mercutio is brave. This is because he is listing a quality Mercutio has and is saying it before his name.
Benvolio also seems to be repeating himself when he says noble prince once again when continuing with the details. He didn't have to repeat it over again but it adds emphasis to the story. He also repeats himself once again when describing what occurred but in a less poetic and more serious fashion.
Lady Capulet's grief also adds to the dramatic effect as she lists off the dead man's relations. This appears to be an anaphora when she says "O".
Once again, just like Benvolio has, she repeats what she said earlier except in a more easy to understand and less condensed form. This is only adding more emphasis.
Once again the prince asks what happened to Benvolio. He already asked this at the beginning but he is using more emphasis.
Benvolio speaks to him poetically. However, at the end of this line, it also describes the way he said it and how he postured himself in front of the prince. This is adding more onto the dialogue.
Beyond this point I don't get the rest sorry lol
