Hope i spell those spells right.
It is certain that Crystarmum can be used by Iris or Talia since it's a basic, possibly well-known, defensive spell in LoliRock. Izira was shown to use this spell in Home Part II besides Auriana.
Crystal Veritus (I believe you are referring to this spell if I'm not mistaken) is a possible spell that Auriana and Iris can use. But realistically speaking, it's somewhat unlikely that they will use it since Crystal Veritus is only used for informational/interrogation purposes and it doesn't fit Auriana and Iris' style of spells that they prefer to use.
Unless you are writing these spells in a fanfiction or some sorts, then any spells can be uses by anyone if you put some sense into why they will use them.
