The variegated plant is a type of Aglaonema. Its common name is Chinese Evergreen. The dracaena looks really bad, when any type of houseplant has leaves that are turning yellow and brown like that it is always a watering problem. My guess is that it has been kept either too wet or too dry - or both When your house plants are dry, a "cup of water" isn't enough to properly water them, you need to saturate all of the soil in the pot and then let it dry out again. Never set houseplants on a watering schedule (once a week is not how to water!!) Water them ONLY when the soil becomes dry to the touch. If you think your plant will be alive for one more day without watering it, then don't water it!! Overwatering plants is the frequency of watering (too often) and not the amount of water given at any one watering. When any plant has yellow and brown leaves like your dracaena, fertilizing it will only make the plant worse because it is under so much stress. If you were to take it out of its pot and look at its roots I am sure that most of the roots on it are dead. Fertilizer is only for healthy growing plants.

Hope this helps, good luck with your plants.

They only became my plants YESTERDAY, which to be fair I was not clear about. Had to dig them out from behind and under like 2 dozen fake plants and decorations on a couple of tables, and hope I didn't miss any. My neighbor was sadly an alcoholic as well as a hoarder so didn't even take most out of their nursery pots, but at least these were still alive. I had seen her a few years back with an orchid, a pothos, and 2 young FLFs, but as they were not there I can only hope she gave those away before they died.

The cup of water was just for the not-pictured Christmas cactus also rescued from her apartment, which was in just an inch of packed, dried out, regular potting soil. It was still green but deflated and limp, but its now reaching up toward my grow light so I think it will be alright. Had I given it more than that it would have been too much. The two in the picture are in my shower because they needed a soak while being able to freely drain until I can get them proper soil and pots, which, along with not having had these plants before, is why I needed to properly ID them. The chinese evergreen was probably bought recently along with the (also not pictured) snake as both only had a bit of yellowing on one leaf. I plan to trim the dead and dying leaves of the dragon tree while repotting, but its starting to perk up already.

Now to go acquire a big ol' bag of cactus mix and small bag of peat based regular soil (already have proper pots, including a big ol' elephant one also from the neighbor)!

Thanks guys!

Both of those are very hard to kill and dead easy to grow, so they should recover, I think.

Much better! Now you'll also be able to see if the yellow progresses. I think you have Aglaonema commutatum and the Dracaena may be a "Riki'.

Thanks everybody!

I'm looking forward to seeing if its indeed a 'rikki' as I really like variegated leaf types. And smh at the former neighbor having it and 5 corn plants (rehomed with other people) in her small studio apartment...growing a forest she would have been if she'd taken care of them. On second thought, that would actually be awesome...if she'd taken care of them.

And funny that the snake plant is also now classified a dracaena. XD
