Yes, those are my best guesses. There is a similar jade called Hobbit which is also a possibility. The dark green plant may become a small bush with time and space. The lighter green plants could be a few different things (they don't really stand out to me) but probably will grow a bit of a stem and end up sprawling sideways over time. Provide the strongest possible light you can indoors (like right next to your sunniest south-facing window).
