Too matchy and cutesy in my opinion. I don't necessarily hate all names starting with the same letter, but these all have similar sounds, yet don't seem to go with each other, style wise. More like they were chosen only because they were matchy for a set of triplets.
As far as the names go on an individual basis, the only one I like is
Benjamin.
