Answer 1

looks like the cabbage white butterfly caterpillar. They have multiple variations, though black dots are usually common throughout all insects, and those are spiricles, which are the caterpillar's air holes. Try some cabbage or lettuce. If it does  not eat those, then it is not a cabbage white butterfly. It will eat the plant where you got if from. LOL

Answer 2

IDK. I hope you are not planing on keeping him as a pet. That is mean >.<

Answer 3

could be a cabbage white butterfly, feed it the plant that it was eating from (the plant you got it from)
