Does this use my data on my iPhone?

I'm new to smartphones. And i was wondering if i'm in the car for example, and someone is sending me messages on skype, liking my instagram pics, etc, and its popping up on my lock screen, does that take my data? If so how do i turn it off.

also can you please list things that take up data?

Yep, that uses data. On an iPhone, you can go to Settings > Cellular, then scroll down and disable cellular for any apps you want. Just to make sure you know, texting with the built-in messaging app does not use data, unless you have iMessage enabled, and/or you are sending pictures/videos. Any kind of social media apps, iMessage, any weather apps, any browser (safari/chrome/etc), or anything that relies on internet access, unless you are connected to Wi-Fi, will use data.

It does but just text takes really little amounts, stuff like skype if its video takes alot of course
