Tillandsia ID

Do these look like Tillandsia setacea? The two on the left in the first photo were ordered over a year ago as Tillandsia setacea.  Since 2 out 3 that were left outside survived the Arctic blast around Christmas, I decided to order more from the same store (clumps on the right in first photo). The newest plants don’t look quite like the originals, and was wondering if anyone had an idea if any or all of these are T. setacea. The second photo shows extra/free plants that weren’t labeled.

Are they known to be cold hardy? I read zone 10, but there doesn’t seem to be a lot of hardiness information for various Tillandsia. I mounted 3 of these outside last spring. The temperature dropped to 8.4°F one night over that Christmas Arctic blast. The 2 that survived were mounted on a Juniperus virginiana limb and near the base of a Pinus taeda. The one that died was on the trunk of a Taxodium distichum. Maybe frost sensitivity? I still wasn’t expecting any of them to survive that cold though. The one on the eastern red-cedar even rooted to the limb last summer and didn’t need the fishing line anymore (Photo).
