OBL, for me, has only a few pointy leaves like that. Mine are rounder, but yours could be younger and they do change. The coloring looks about right for this time of year. 2nd one depends on the size of the leaves. Very likely NBC. -Babka

melo7me - Euonymous fortunei will creep over the ground but if it comes across something like a tree trunk or fence it will climb, just as English ivy does. The id is not a guess, it is definite. It is unlikely to thrive as a house plant. The term doesn't simply mean a plant that is brought indoors. It is specifically used to denote plants which can actually thrive indoors. Those that can are usually from low light situations in warm climates which echo the conditions inside a home. E fortunei is not one of those. Note that your friend had this in their yard, not in their house. Euonymous fortunei

Thanks, Todd. :) Could the first one also be sedum lucidum obesum? From scouring the net, was finally able to identify the second and fourth plants. Second = crassula congesta Fourth = othonna capensis
