I'm not convinced that any of these, excluding the fat snakes, are particularly realistic. Herbivorous snakes aren't impossible but we need more than "their teeth changed" and making a beak from the skull is pretty unlikely.
The swamp dragon is okay but why does it need nose-tubes? No known aquatic snake, past or present, possessed such a feature so I find it highly unlikely that such a structure would evolve.
I fail to see what the 'oars' do for the oarsnake when actual swimming is a far more effective form of movement. The fused fangs could work but why? Stronger jaws and blunter, thicker teeth would be more practical to a turtle hunter. And why turtles instead of the countless other, softer, easier-to-eat lifeforms that a snake could hunt?
I like this idea. This sort of behaviour could potentially evolve from breeding balls, perhaps originally as a way of males securing a mate in the midst of a breeding frenzy, but there needs to be explanation of how it evolved.
