I need to know what type of junipers these are so I can look for them by name. I know they are junipers but I just don't know what kind of junipers. I need to get the exact same plant because the limbs are not growing back in some of these.

Hard to tell without a close up of the foliage, and the fact that they've been trimmed into a hedge shape.
Try comparing it to some of these

It might help to take a cutting of one to a nursery and see if they can tell which one it is.
