3rd is crassula campfire, be careful ants love this plant and where there are Ants their will be mealy bugs!
Like strong light to keep its nice shape and color, but can get burned very easily in to strong of light. Very very easy to stretch without prope lighting, i would know. I've saved a few in my day and they were severely burned and stretched hoping this year i can snip off the tops that are compacted and re-root them to look like yours, cause that's how they are intended to look!
