I believe these two are not sedum, but delosperma species. They would be easy to discern from the sedum in the mix. Hope this has been helpful? Let us know how your final year project goes.
This site has a photo of Delosperma hallii and some other species delosperma. It will give you an idea of what to look for in the leaves.
