Help needed with reformating trance tracks to play at 1:4

Im new to using Audacity so apologies if this is an obvious question to fix. I have a 1hour contious trance playlist which i have sperated into 8 individual tracks. However none of the seperated tracks are in sync to 1:4 ( 4 beats to a bar) and the chorus is now coming in at a different time. How can i fix this as they are impossible to mix with. Any help is really appreciated.
