It looks like a stapeliad. Could be a few genera. You'll probably have to wait until it flowers to get a good ID. It should like strong light (indoors that would be as much light as you can provide), good drainage, and water when the soil is dry at depth, but not much sooner. I would not repot at this time. Wait a year maybe?
Now is a good opportunity to look at the stems of your plants (several rooted cuttings in one pot, from the looks of things). Look at the vertical distance between the bumps along the stem. That distance (the internode) is a great thing to monitor to figure out whether your plant is getting enough light. On the 3 longer stems, especially in the first photo, the lower part of the stem has longer internodes than the upper part. The tubercles were further apart at the beginning, then started growing closer together at some point in the recent past. That tells you most likely that they experienced an increase in light corresponding to the slight change in shape.
If you continue to watch your plant over the coming months you can see how its current exposure compares to its past exposure, as evident in the internodes. That gives you a good idea if you are providing enough light. If the internodes continue to be short, your plant will be compact and more likely to be healthy. If they stretch much further than they were at the bottom of the longer stems, consider relocating your plant to provide more light.
