Succulents to the left of me, succulents to the right!

Succulents to the left of me, succulents to the right!

It was almost 3 years ago, I believe, when I first got my little succulent window display and posted pictures of it here in this community. That's when I found out the pretty flowers on top of some of the plants were glued on straw and the strange formations on others was grafted on. Now I'm wondering of the grafting can be undone. Succulent left Succulent right In one picture a light green thing sits atop a four cornered barrel thingy and in another picture an orange thing sits atop a the same kind of barrely thing. Can I seperate them? How? Any advice will be appreciated. And I now the salvia isn't a cactus. He's there because I didn't know what else to do with him.
