Hi Thea, I think the one in the first container the one with pointy tips at the edge is a type of aloe, that is the only one that may be iffy this winter. The last two looks like some type of Agave, those can easily bear our mild winters.
You can still add a little more pumice or chicken grit as top dressing for your soil, to further protect the plants. I have been adding some more on my plants left outdoors lately. I have been putting my succulent containers outdoors, the one that I can still move as close as possible to our house, and fingers crossed after that.
I am just tired tonight after all this final move in.
