Only one we actually saw get hit by it was Koichi. Although, I'd assume he hit Okuyasu and Akira as well. I think Akira was the one who went stand-happy with the bow and started shooting everything.

I think Akira and Toshikazu wanted to kill Jotaro simply because they saw him as a threat. Obviously if they're just a bunch of delinquents who want to do some unlawful things, someone like Jotaro would try to stop them. I don't think there were any ulterior motives, although I havent read part 4 in awhile either, so I could be wrong.
