Is friendsim canon? If so when does it take place? I always thought all the trolls shown in friendsim were from the past (condy ruling era) and are henceforth dead now

“Condy ruling era” literally is not a measure of time because we’ve never known an era of Alternia’s history not ruled by Condy. It takes place slightly prior to Joey’s arrival to Alternia, but its canonicity is dubious at best.
