is it possible to add more of those roaming students than the usual 6?

The original comment was referring to roaming students, such as the two gendered preys, Student Predators such as Bella, Tulpy, Satie, and Ligeska. That adds up to 6 in total.
Two Random Normal and Two Random Nightmare respectively (Including the easter egg challenge on the latter) does not unlock anything, it’s an optional mode after completing all 4 main predators’ normal modes.
