To remove the Facebook Messenger app from your phone, you can just hold your finger on the app until the apps start to wiggle and an x appears in the corner of each app. Tap on the x of the app you want to remove. You can also connect your iPhone to your computer and go into iTunes to remove the app. This process is helpful if you have several apps you want to remove at once.
