How do I transfer stuff on my iPhone 5 to my computer?

ITunes

Sync it with itunes on your computer.

First, download iTunes on your computer. You can get that here: http://www.apple.com/.../download/
After you've installed it in your computer, connect your iPhone using your Lightning to USB cable to your computer and open up iTunes and click on your device (iPhone 5). First, do a full back-up to your computer by clicking, 'back-up' next to where it says, 'Check for Software Update'. After all your data is backed-up on your computer, go to the top-left corner and click, 'File'. Scroll down to where it says, 'Devices'. From there, select 'Transfer Purchases'. Once that's done, iTunes will sync your Device & you will be done.
