From the analysis of the video the girl was lured by one of the guys for sex for cash but unknown to the girl she was going for more than she bargained. Listen to her request 'Nna ye zie num the thing' what was the thing she referred to. Again you could hear her pleading that she cant recollect offending any of them. Then the repeated plea that they should have mercy on her because of her aunty Again you could hear her plead that her father will settle them for any amount. To which one of them said they are not kidnappers and then  bragged that he is a 4th year student. The other said he was an IT student and he needs cash. Further more you could see them taking turns on her to which she said she was trying.
The conclusion here is yes, those boys are very much likely to be students but for the girl that is still doubtful, but onething this is clear she said 'particularly you Uchenna' which means that she knows at least one or some of them.
The only way to uncover this riddle is to track the girl down and force her to reveal the identity of the said Uchenna who will in turn fish out the rest. Right now from all indications she might not be courageous to tell anyone because its a game she has been playing but this one was a bad case for her.

Looking at the video, only one guy was probably using his phone to record the scene hence the unsteady pix. I think the guy cleverly edited the porn movie and sent it to his partners in crime and then it got into the larger school community and then rumours started making the round that a female student was a victim.
If the girl in question is a student, in my opinion since her face is visible a fellow student should have identified her, but she is not which gives credence that one of the guys went to town to import this one, what they call bush meat in school palance.
So its over to the law enforcement agents to burst this case if they got what it takes.
