I recognize no numbers in this list. If they are at one of the regionals you are attending, find them on Thursday at the event. As for website, look in the Regionals section of the FIRST website. Under each regional, there should be a team list. Open that, and if a team name/number is listed in blue and has an underline, that team has a website of one form or another, be it school or team.
Nicknames for the team will probably be listed on their website. If you can't find any information this way, I can't help you any more, but someone else probably can.
