NOTE: Removing an ICON from the screen does not remove the app from the device. To do that you need to go into "Settings", "Apps", "All" and locate the app you wan to install. Tap it and then tap "Uninstall". If you do this, for any of them, that would also remove the icon from the device.
However, if you are just wanting to remove icons, all you need to do is "Tap" and "Hold" the icon on the home screen. As you are holding it you should get either the word "Remove" or a little trash can on the upper portion of the screen. Drag the icon to the word or trash can and then let go. It should no longer show on the home screen.
