For "Gratiola" and Limnophila aromatica, I would top and replant the healthier cuttings. You can most certainly try letting the rooted portions grow out if you want --they will produce new growth.
As for the E. quadricostatus, I don't think you can prevent that unruly bunching on the glass sides. You will just have to trim off all the excess growth with scissors or try to pull it away from the tank sides with your hands.
