I have been to most of the places above in Bali. It's a shame that the island is congested, roads are awful with too many motorcyclists, and the south of the islands where the beaches are looks shambolic. There are clean up operations underway on some of the beaches regarding pollution especially Kuta Beach. We stayed in Nusa Dua which wasn't too bad when we went there. The first picture of the Pura Ulun Danu Bratan Temple which is iconic for Bali - that is a must visit even though it is crowded. One of the pics is the many rice terraces on the island although the most popular is Tegallalang. The second pic is Mount Agung.
The last picture is Komodo Island - I'm pretty sure of that
