So Ava does nothing? Please concretely state what your character is going to do, don't just ramble lol

1. is there any way to communicate with someone outside of the academy without leaving it? Are there telephones, telegrams? Is there some sort of communication magic like the scenes in The Last Jedi where (spoiler, highlight if you dont mind) Rey and Kylo talk through the force? Is there some Hologram illusion magic? It would be useful for Hitojo to communicate with his family and the people that his family associate with about the corporate meddling of the academy's administration, staff, and students

There is basic technology, such as radio, telegrams, and telephones. The academy has three public phones in the Entrance Hall available for student use. The answer to whether there is communication magic should be apparent now that the basic workings of magic have been explained.

2. is there some magic skill where one can expose the true form of someone else? I am thinking of using it as a plot device for if Hitojo or Akihiko interrogates has a private meeting with Ava about her "retardation" and they use some magic to find out shes an alien

That depends on how Ava is hiding her identity as an alien
