Romeo & Juliet Act II. Scene 2

2.     
  When Romeo says that Juliet "Speaks with her eyes" he means that she does not need to talk to say what she is feeling. Juliet is showing everything  that she is feeling clearly in her eyes, so she does not need to speak for Romeo to understand what she feels.
3.        
When Juliet leans her cheek on her hand, Romeo says that he wishes he could be the one touching her cheek. He wishes he was allowed to be with her and and love her without there being consequences.
  4.     
 Unaware of Romeo's presence, Juliet asks him to forget about their families' quarrel and choose instead to be with her. She says that if he chooses to not be defined as a Montague, then she will, in turn choose to not be a Capulet. this means that if he forgets about the things that are keeping them apart, then she will too and they can be happy together.
  5.   
   Juliet says that her name is her enemy and that Romeo is who he is and that his name is just a name. What she means by her name is her enemy is that she could be with Romeo if she had a different name. Her name is keeping her from the love of her life, and thus, it is acting as her enemy, blocking her way to what she wants most. What she means by someone is who they are no matter what their name is is that even though she is a Capulet, and Romeo is a Montague, it does not mean that they are  enemies. their names do not define them and she wants Romeo to know that they should not let their names control their lives.
