Yes, two layers can be processed at one time, in either the boiling water bath or pressure canner. The University of Wisconsin Extension Service, however, recommends against double-decking for water-bath canning: “We don't recommend stacking jars in a boiling water canner because the water movement may tip the jars.”
Regarding this, can you double stack jars in a pressure canner?
Yes, you can stack the smaller canning jars in a boiling water or pressure canner, just not directly on top of each other. The stacked jars in boiling water canning still need to be submerged in water with one to two inches of water above the tallest jar in the canner.

More air in the mason jar means more oxygen is present to discolor the food and promote rancidity in fats.When Canning Do you turn the jars upside down?
Leave the jars lightly sealed during the whole processing, and when the time is up, remove one at a time from the canner, seal tightly, turn jars upside down, and set aside. After screw top jars cool, do not tighten tops again as the seal will be broken and contents will spoil.”How do you reprocess unsealed jars?
