Yeah, I pretty much agree with you all
Tomoe Hotaru (Saturn) INFJ 4w5
*As stated above, she's not very well developed. The creator describes her as, "delicate, quiet, precocious and expressionless." She literally has the power to destroy a planet, so one might need extraverted Judgement to handle that kind of responsibility Also, I imagine that INFJs and INFPs can seem equally withdrawn, but Ne (in my experience, at least) makes INFPS someone seem more flightly and expressive.
Tenoh Haruka (Uranus) ISTP 8w9
*Obviously, her "need for speed," and flirtatiousness suggest Se, but she has refined that function to running and racing too greatly for it to be dominant.
Kaiou Michiru (Neptune) INTJ 1w9
*Neptune is extremely self-controlled, independent, perfectionistic, focused These qualities indicate Te, to me. However, I believe it is secondary to Ni, which enables to deal with large amounts of abstract information. Thus, academically, she rivals Mercury, but her intuition leads her to pursue fine arts. She presents a graciousness that resembles Fe, but I suppose she proves it to be more like thinking when she, somewhat coldly, accuses Mercury, a true IFJ, of holding back in a swimming race. She's also calmly willing to compromise anything in order to achieve her and Uranus' goals.
Neptune is easily my favorite.
Meiou Setsuna (Pluto) ISFJ 1w9
*Again, a somewhat more generic character. She fulfills her duty as the Keeper of Time without complaint, but is described as looking "lonely." She is standoffish, but helpful towards the Inner Senshi, especially Chibiusa.
