If I use airplane mode with Wi-Fi, will it use my cellular data (iPhone 5c)?

I have a iPhone 5c on AT&T and I recently got a text saying i've used 90% of my cellular data and if I go over they will charge me. If I use airplane mode with Wi-Fi and use apps such as snapchat, Kik, Twitter… Will it be using my data up?

I turned cellular data off on my iPhone and turned on Wi-Fi. I'm allowed 7GB of data each month and the cell carrier told me not to make and big downloads or stream videos or it will slow my internet down.

Why do my iMessages take a long time to notify me on my iPhone?

I have an iPod and a iPhone both linked up to iMessage with the same number. But with my iPod I can only chat with purely iMessage.

I have noticed that my iPod dings instantly when an iMessage has been sent to it. But my iPhone however, doesn't give me a notification until 3 to 20 minutes later.

This situation bugs me a lot and I was hoping for a way to fix it.

I tried turning off iMessage on my iPod along with turning it off but my iPhone still receives it very late.

Any solutions or other experiences will help.
