Delicate Green

I destroyed my plants about 90% thinking they had to go, but changed my mind. Can I revive them? HELP!?
I have two plants, house plants,a Dracaena Janet Craig and a Chamadorea Seifrizzi,….the former is a delicate green leafy plant, and the latter is a household Palm.
I cut off about 80-90% of the stems , with leaves attached, getting ready to dispose of them, and there were still a few minor plants in the pot.
However this morning, I decided that i wanted them afterall, go figure, and now feel horrible about getting rid of them,
Will the remaining plants in the pot grow and eventually fill out,
and will the cut off stems survive if I put them in water, or try to resoil them, or are they good as dead?
What should I do?
I put the stems in water, and got them close to the sun.
Will they grow roots?
What should I do? Help!
As long as you didn’t do too much damage it should still grow
