That is a good looking jade, though if those are independent trunks there, it does seem quite overcrowded.
I guess it will depend on one's preference, you can keep it as is. Seems it is managing it. If you want to repot some, it is as good time as any to do it, since it is Spring...or you can just leave it as is. They have such shallow root mass anyways, so they are doing well. The only thing is, the more branches it makes to reach out for more light, the more entangled all of them will be.
Though ideally I would separate them into their own individual containers and got to make the media much more grittier and well draining. I would then use a more wide mouth container than a deep one, and always with drain holes.
My Crassula ovata easily dominates one container and its trunk gets very fat too. But I do grow them outdoors year round so it has much better sun exposure and overall ventilation.
If your plant is grown indoors, just be careful with watering. That media does look too dense to me, but it seems the multiple Jade trees are sharing the moisture effectively so all are still doing well. Though it could certainly do with much more light access. The leaves are too deep green, which to me indicates it is not getting enough light.
