I cross posted with you Greg and Anna.
Anna, looks like the lower leaves died. Once they start actively growing again you can decapitate the tall one, let the cut heal over and lay it on the soil. It will grow new roots. What is your weather like now?
I notice you have them in containers, you might rotate them occasional since they are not in full sun. They start leaning towards the sun unless in full sun. But your summer full sun would probably kill them. In the winter you could possible place them in full sun?
Your 'Emerald Empress' is really showing some nice coloring.
