Ina and Gura got to hang out a lot in Japan, Mori and Kiara go out eating often when they meet, and let's not forget that time when they went to the enjoyment park together. Ina clearly talked about being happy to have friends like them because of how rare it was for her to have relationships like these in the past.
If these aren't friendships, I would at least describe them as close acquaintances.
