None of them have released, they're all rougher prototypes than Aishteru except for maybe HeatWave. They're about as cursed as Legend of Krystal successors.
You have to survive a handful of waves to make them all spawn at one point. First is the pumpkin man, then the flytraps, then the Nyxes (i think that's what they're called), and then the lycanthropes. That's all the enemies so far.
