The main characters (Osamu, Yuuma, Chika, and Jin) each get a character profile page in the manga volumes where these information are revealed. All the other characters are introduced with this information on their team profiles. Some of the information, like birthdays and blood types, are on the official website too: http://worldtrigger.info/article/border.php
