How to stop all apps updating on iPhone 5?

I clicked "update all" and none of them have updated yet! It just keeps saying that they were unable to install. Some have the bar half filled (been like that for two days though), some say waiting and some just say the name of the app but are blurred out though so you can't click on it. How can I stop this? I don't mind if it will cancel the updates, I just want to be able to access the apps because I can see that people are messaging me on whatsapp and I can't get on to reply.

Try a force shut down of your phone then power on and begin with the installation process, it will be normal and faster too, It happens with mine and I do the same, so you can try it too.since installation becomes faster you can finish it quick and use other apps

I actually never click the update, not unless there's soemthing added I really want.
