To go to my profile, you would click on Arena, and then under the six random people they give you, there should be a seach button click on that and it will open a bar for you to type in. You can type in my name Phoenix_Oasis or whomever else you're looking for. I think to get pupils, you have to recruit people. You recruit people by entering your "website", for example mine is http://phoenixoasis.mybrute.com. If you didn't have one already, you could make a new character up to challenge mine and in the same notion becoming my pupil.
