How do I close down the apps I have open on my iPhone 4

How do I close down the apps I have open on my iphone4

Why do you want to close them down? They aren't using any power, and leaving them on standby (as they are when not actively being used) makes switching apps much faster. Instead of pressing HOME then navigating to the next app you want, possibly opening folders or changing pages of the Home screen, when you want to switch double-press the HOME button, scroll to the next app and tap it once. If you are switching frequently between a small number of apps (like Mail, Facebook and Twitter) this is much faster, because the Quick Launch ribbon (that's its official name) puts the most recently used apps together.

How do I close out my apps (Facebook, iTunes,etc.) so I don't run up my data usage?

Generally just tapping the home button when in the app will close it. However, I feel you are referring to closing in the multi-tasking tray. Tap the home button twice, the list will come up. Then swipe upwards on the thumbnail of the app and it will close.
