Yes, except the last two. You should read Arthashastra only if you like Plato and Machiavelli.
The first two are essentially "hero's journeys" like Odyssey, the suggested translations are good. The 3rd is like Aesop's fables. The fourth is good if you are interested in Buddhism.
There are some abridged versions which tones down the religiosity and are targeted at younger and western audience but that make them somewhat lacking. There are also some comics and anime. You can read them and go back to the source material, if they interest you.
