Duplicate icons for one app

[AC Question]

I accidentally downloaded my facebook app multiple times. Now I have four icons on my home screen

Those Facebook icons in your home screen are just shortcuts and not the real app. You can delete them one by one. Long press on it and drag it to the delete/trash icon on top of your screen. In some phones and launchers the long press will prompt a menu with the delete option included.
