Congratulations on getting your license. I would suggest going and sitting on them to see how they work for you, which is hard to determine from looking at the pictures. All the bikes are old, so the probability they will need maintenance soon is fairly high. Is it worth it? If you want to learn to ride and can't spend more money, I would say yes. Pick the one you like and make the best of it is about all you can do. If you can bring along someone who knows about motorcycle and what to for, that would be useful. Good luck my friend and welcome.
