Thanks for the photo update wiseswords. I do wish you did not add heavy sand there. Perlite will be enough to open the soil. Anyways you have added it already. Just observe later on if the soil packs up again too much, sand has the tendency to do that in the media.
Looking at all the photos, the plants look okay, typically they have really a small rootball, that is why next to the proper use of media, the container size follows, find the smallest container you can use. They take awhile to grow their roots. I see the plants have good stems, nothing seems rotting, and leaves still green where it should be, so it is okay as I see it.
Thanks for updating your location, now I understand why you have it indoors. Just continue repot and keep it near a south facing window, water till it comes out of the drainage holes, and set aside. Then leave it alone to recover from all the root disturbance.
Yes, you can get a leaf, twist it off so you get the petiole. I would just lightly dab the space where it come from with cinnamon. For the leaf you removed, rest it on top of new media, in part shade and eventually the leaf will either form new roots first or new leaves. The old leaf will continue to provide energy to the new growth and will eventually dry out. Just water lightly, not too often, it just needs very mild dampness.
Here's a sample of my jade leaf cutting that I have rooted in Jan 2013:
started indoors
By late Feb 2013, I have brought it outdoors, and this was photo on April 2013, new little leaves forming at the petiole end:
It is now 2 years old, this photo last 07Jan2015, has been staying outdoors here since 2013, old leaf is gone now, and it is now a little plant with its own stem and set of leaves.
Hope that helps! Good luck!
