I see... well is there a way to reform any of these 2 in order to make it closer to a bonsai?
Welcome!
Well, I guess the braided one will never be a bonsai, even if you cut it hard and very low.
The other one could be a bonsai someday, but it will take a lot of expertise and years, many years. And in the end could be a not-so-good bonsai.
Study a little more, and buy some material more suitable for bonsai, there's no other way.
