I can't quite make out the right specimen. Assuming is is only a dark-colored (practically "sard") bead, I would say that these are all examples of carnelian (or cornelian, if you prefer). There would be no harm in calling the left specimens "yellow carnelian," in my opinion. Some of your specimens provide good examples of beads that are "carnelian agates," as well as non-banded "carnelian chalcedonies."
