All For Gardening: I don’t remember what this plant is called, also help, it’s leaves are getting shriveled up underneath the bigger ones to the point I had to pull them off..

What type of soil does this succulent need? How to water? I’ve kept it alive but barely. I have a similar problem with nanouk plant. I’ve had these plants for about 5 weeks and been watering them about once a week but at one time I left the nanouk plant out in the rain so twice I was having to let it sunbathe about 2 days a couple times after it got too much water. But these beautiful plants are barely hanging in there…
