alright after some misunderstandings from me reading one of the questions wrong,
first the simple question, uniforms are being drawn as of right now but you can pull a Kaito and just not wear them though he still wears a bracer with his dorm emblem

the second and third question is this, You can only issue a challenge to the person above you and the challenged person can refuse, but they will give up their rank if they do. however, you have a limited number of challenges you can issue so the challenger has to be confident
