If both purchase tickets for the event you can choose the section and seat. The best bet is to both check if single seats are available most tickets are sold in pairs.
If the seat is available, absolutely
Its possible if you order from the same app. Better yet, you purchase the tickets and have your friend reimburse you. Best way.
Nope no chance! Try to buy all the tickets together
All seats are numbered and the each row lettered. Which means no chance to change sits unless you get lucky how Oscar Camarena said.
If your lucky that someone switches seats yeah if not u sit where your tickets are at
