Multiple different speedrun ghosts at once

[Guymcguy087]

so I want to know if its possible and if so, how to make different (and possibly multiple) speedrun ghosts do a run of a level at the same time, ex. a Sonic, Tails, and Knuckles ghost each going through their fastest time in Green Flower Zone act 1 at the same time

I'm not sure if there's a way to watch a replay with multiple ghosts, if that's what you mean.
If you want multiple ghosts to show while you're playing, go into record attack and click "ghosts." Then set "best time" to "show all." This will show the ghost replay for each character's fastest time.
