What heroes have been added since launch?

[Dishonored Guard]

And if possible, I would appreciate it if you could mention them to me in order of release.

Mirage

[Foxassassin]

Holiday and Calico seem to be very close to completion with Wrecker needing texture work. Wondering when they'll release, honestly.

"Launch" isn't even accurate; this game was supposed to still be in secret early development right now, but people leaked it and a bad coding issue made it so anyone could be invited to play it.

Mirage is the only "officially" released new character. Since there are some dev tools included in the sandbox mode, people used them and found some upcoming characters who are already fully functioning; several just need texture and animation work to get them to early access standards, while others still have unfinished abilities and placeholder copy weapons.
