Messenger and other apps not working, how can I get them working again?

Messenger and other apps not working

When I go onto messenger it is fine but when I tap on a message I have, it goes to open it but then says "Messenger is not responding". This is also happening with messaging (texts) and email. In addition, Snapchat logged me out when it updated and when I try to log back in, it also says it is not responding so I uninstalled it but now when I try to reinstall it, it says " unknown error with coding" or something
