In Windows Phone 8.1, notifications from all apps (including Facebook) appear in the "notification center", which can be accessed by swiping downwards from the top of the screen even if the phone is locked. In addition to this, you can also set the Facebook App as your Lock Screen provider in Settings > Lock Screen > select the app you want to be shown in the lock screen.
