I have several succulents and need to ID a couple of them and determine what I should do for one of them

Plant 1:

Plant 2:

Plant 1 has opened up in the center and I think it need to come out of the pot. One of the bloom heads broke off and had air roots, so i potted it up. The stem/trunk is a dry tube like structure.

I am in Sunset's Zone 9, near Sacramento. They are all in pots on my front porch on the south side of my house. I think the burns my be from frost damage but could be sun burn (less likely given location)

I have considered planting these in the yard, near the house, about 5 feet from the porch that on on in this photo.

How much frost can these take and would a burlap cover or light be required on hard freeze (32-28F) nights.
