Unfortunately there's no big compendium with all the juggle potential of characters' various attacks that I'm aware of. Your best bet is shoryuken wiki's individual character frame data pages, which will sometimes have the JP number but usually just "pursuit property" or "can juggle". There might also be a thread somewhere on shoryuken forums collecting them, get back to me if you find one.
A much better juggling video, though more complex: https://www.youtube.com/watch?v=a9MR3OPzo8I
