The answer is the following:
Friar Laurence: He hopes that the marriage of Romeo and Juliet will end the hatred between the Montagues and the Capulets.
He agrees to marry Romeo and Juliet, and tries to help them to come together through the use of a sleeping potion, which finally determines their fate.
Mercutio: He is disgusted by Romeo’s refusal to fight when challenged and dies cursing the Montagues and Capulets for his fate.
Romeo's close friend, he makes fun of romatic feelings and ends up blaming both families for his death.
Lord Capulet: He is the head of a powerful family. He threatens to disown his only child for rejecting an arranged marriage.
Juliet's father wishes that she marries Paris.
Prince Escalus: He is the ruling authority of Verona. He decides that Romeo will not be executed but only banished for killing Tybalt.
Since he is a friend of Mercutio and Paris, the Prince does not carry out a death sentence againt Romeo, but is concerned with keeping Verona free from violence and disturbance.
