I kinda get how they are determing whether each is an acid or a base, but idk if they are getting their info from somewhere to ensure that they are acids or bases. Especially for part d, how is KBr nuetral while KF is basic?

To my understanding, KF is basic because F- is an exception, being the only halogen that can affect the pH of a solution. I believe this is because F- can form stronger bonds than say Br, even though they are in the same group. My knowledge ends here though, if anyone has a better explanation.
