Here are some more examples of bar chord extension shapes. These are just to give you an idea of how you can change any open chord into a movable bar chord shape. There are still hundreds more variations you can have and the best way to learn them is by songs. Don't try and learn and memorize every chord there is (there's just too many), find some songs with interesting chord structures (like jazz songs) and practice changing between the various chords.
