Wow, that's hard to answer...haven't read the play in 4 years. Umm...Ok, the Exposition is like, the setting up of the play. I'd say that's the revelation of the rivalry between the two families. Just like the Denoument is the wrap up...you know, the whole "Juliet and her Romeo" thing. Now, I'm not sure about this, so don't hold me to it.
The rising actions, while i'm not sure just what they are, are the scenes where the tension mounts. Scenes with battles...the first climax could be tibalts death, when Romeo kills him. The second could be when Juliet kills herself...wow, that play's violent.
The falling action's the opposite, things cool down...
Types of love? Umm...romantic, friendship, and parental? I have no idea, really.
Structure? All I remember is that in the third act, that's where the biggest stuff happens.
Wow, I'm sure I've been absolutely no help at all. Sorry about that. I took a crack at it.
Well, hope it all works out!
