Crinums are reliably hardy here, so no problem with those. One of your succulents looks like 'Francesco Baldi' which can handle temps into the teens and stretches of 72 hours below freezing.
Graptosedum (XGraptosedum 'Francesco Baldi')
That pot has plants that have been outside for many winters, although that particular arrangement was just put together last year and it stayed right where it was all winter, unprotected from rain. The other plants are:
Jenny's Stonecrop (Petrosedum rupestre subsp. rupestre 'Blue Spruce')
Sedum (Sedum kimnachii)
Sedum (Hylotelephium SunSparklerยฎ Firecracker)
And this which, if it is still alive, will manifest as new growth from the roots. The stem from last year is a goner. Some Sedums do that normally, so IDK if that was normal for here for that one or not.
Stonecrop (Hylotelephium spectabile 'Ayers Rock')
This pot also stayed out all winter, unprotected from rain.
Hairy Dewflower (Drosanthemum hispidum)
And this pot:
XSedeveria 'Pink Granite'
This has also survived more than 1 winter in a pot @ my house. I had this for about a decade but it got too dry and bit the dust this past summer.
Chinese Stonecrop (Sedum tetractinum 'Coral Reef')
