I am shooting an older model Bear bow set at around 60 pounds. It has a new NAP Quicktune 360 with metal prongs and I am shootingnew Carbon Express Terminator Hunter 4560 arrows. All the arrows have the same head and all the fletchings are perfect.
However,One of the arrows is printing perfect bullet holes, two of them are tearing high, and one is tearing low.
What could be the problem?

Check for fletching clearance

Turn your arrows 120 degrees then shoot then do it again.

Well, at first glance it sounds like a clearance issue. If your vane is hitting the rest, it will show up pretty quickly via black marks or ruffled vanes. Are your arrows fletched offset or helical? Make sure your vanes are clearing the rest.

Also, you don't mention how long your arrows are, but you are kind of on the border with spine. You may be a bit underspined. Normally, this shows up as a left/right tear and not up/down, but it could be part of it. But, since you have 1 arrow shooting well, my bet is on vane clearance.

Did you spin your arrows ? it might be one of inserts or the badly cut arrows.
Try and find out if the arrows and tips are straight on a magnet or use an arrowspinner.
