Nah, Kirby shouldn't be listed next to my name. I didn't feel confident in my Kirby after lack of practice last week and when I lost MMs to Sin and Korn with Kirby, I decided it'd be best not to use him in bracket.
My brother used Jiggs, but I dunno if she should be listed next to his name, I don't know if he won games with Jiggs. XLR8 used Ike and Sonic, but I dunno if he won games with Sonic, I know my brother said XLR8 beat his Jiggs with Ike game 1, so Ike should be listed next to his name. I'm pretty sure Ada went all Marth, he used Marth in my MM with him and I saw him use Marth in his set with Aposl. That's all I know for characters you're unsure about in the OP, Chu.
EDIT: Iota's the only person Luckay beat right? Then he should have Pikachu listed to his name instead of Pit, Iota told me he beat Luckay's Pit game 1, but Luckay beat him with Pikachu.
