What uses data on my iPhone?

Alright, so I have a pretty small data plan. That doesn't really bother me. I used a little over 90% and my bill ends the 20th of January. That's because I didn't have Wi-Fi on. I know that if you play games with Wi-Fi on, it doesn't use data. I want to know if the following will use data when I'm on Wi-Fi. If you could make a list like I did with yes and no's.that'd be great.
