Is it permissible for Muslim students in Norway to take turns attending Friday prayers at the mosque day after day, and what is the Shar'i ruling on that, and what is the Shaykh's advice to them for maintaining prayer?

Friday prayer is an obligation upon every adult, sane, free, Muslim, resident male who has no valid excuse. It is not permissible for these students to miss it due to classes. They must seek permission for half an hour to perform it. Otherwise, they are required to go to it, unless doing so would result in financial, psychological, or livelihood harm. It is permissible to perform Friday prayer outside of a mosque according to some scholars.
