Apps not working/updating

I have 2.92GB available on my iphone 5c but am unable to download/update any apps. It also won't let me pull anything from my cloud. The app store tells me all apps are up to date but I have apps that are telling me I need to update them to use them. Then if I click an update in the actual app it just brings me to the app store, but doesn't update. I have 2 apps on my phone that are not usable, and I can't delete them. When I bring them up in the app store, I click on open and it does nothing. If I try to get something form my "purchased" apps, I click on the cloud, it does nothing. I also get kicked out of some apps while using them. I already did a sync/backup on my itunes. I am running IOS 10.3.3 😕 Any help would be appreciated.

Thank you!
