Thanks for your wonderful response Al. While I am sentimental about my jade plants, it's also having a hard time tossing out even a leaf when I know I can easily propagate it and create a new plant. But I have to get over that. I was also incredibly busy taking care of my mother over the past five years and now handling her affairs after she passed, so I haven't had time to prune.
These are the plant lights I use.

I had them set on the highest setting for 12 hours for over a year and the leaves started coming out thinner and they would curl. So I set the lights to eight hours. I also raised them up so they were not that close to the plants to see if that helped the leave curling. The larger leaves on the lower part of the plant are thick but as you saw in the photos, the newer growth's leaves are thinner and curling. Since you said they want more light then I will keep the lights on for 12 hours (the longest setting) and lower them closer to the plants. But having a strong source of light for 12 hours isn't natural (if they were in a south facing window), so it's interesting how the leaves are showing a lack of light.
All the pots have drainage holes except for one. I am careful not to overwater.
Can't thank you enough for your thoughtful and informative responses Al. 😊
