Q: Null apps!!!!!

MY sister and I had the same Apple ID set for our phones when getting things on the App Store. Sometimes the apps she'd get would try to download on my phone. Sometimes they would and sometimes they would say waiting. When they said "waiting" I would try and delete them. But after a few tries the little x in the corner would go away! So I'd move it to another screen until they went away. After a few hours or so they did. Now I have 4 "null" apps!!!!!!! One takes up 88.3 MGs!!! Another takes like 47, one 43, and the final 33. All in MGs!!! They won't go away even when I go into the settings to delete them. I've done this over and over and over and over!!! They're still there. Any tips so I don't have to completely reset my phone? Also if I do which reset do I use? There's like six different ones!!! Help please!!!
