I don't know the names of the first two.
The first one looks link of sad, its leaves are hanging. It get a little bit of sunshine in the morning. Maybe I'm not watering it enough (once a week).
The other one's leaves turned yellow at first and so I watered it less. Now its stem has got tilted and I have no idea why.
I have a dracaena as well. Two of its leaves developed yellow patches but at the same time a few other leaves developed dry patches. I don't know if I'm watering it too much or too little. It's in a pretty large pot.
