Hi April, and welcome
Yikes, those puppies got seriously forgotten, didn't they? Can't even tell what the first one is, but you can just scrape at the bark on the stem with your thumbnail to see if there is any green in there. If there isn't, toss it and buy something else for that nice pot. If there is, set the pot into a bucket or large bowl of water for maybe an hour, until all the potting mix is wetted again. You may have to "till" it or stir it up a bit as the potting soil sometimes dries to a solid brick when it gets that dried out. Once you have the soil re-hydrated, all you can do is wait a week or two, and see if any new growth starts up.
The hanging plant looks like a Pothos, and there's still a little bit of life there. Again, sit the pot in water for an hour or so, until the potting medium is completely wet again. (you can tell by the weight of the pot when you pull it out). Let it drain, then set it in a spot with medium light, no direct sunlight. Then wait. Once you see some new growth, you could start watering it on a regular basis, and give it some very diluted fertilizer every couple of weeks. Pothos like some humidity, too so if you can keep a spray bottle near it, and give it a spritz or two every day, that will help it recover.
Keep us posted if anything happens! Good luck.
