The non-Jade looks a bit sad. I would definitely repot it into gritty mix. It looks overwatered to my inexperienced eyes.

Thanks! I'll definitely repot them both as soon as possible and try not to overwater the jade too. c:

I don't think the tall one is jade - but if you post a clear close-up, maybe we can ID it.
Other one is in poor shape, I would say it is water-logged. Immediately - don't wait until you get better mix - out of whatever it is in, let it sit on newspaper or some kitchen towels. It is better out of the soil than in wet soil. Succulents can take dryness better than wetness. Should be in well draining mix. Can't tell for sure what it is either.
It may be suffering from lack of light too.
I hope it will recover before you are planning on gifting it.

First plant on the left is a Sempervivum, commonly called Hens and Chicks or Live-Forever. Sadly, it will not under your current regime. This is an outdoor plant; it performs very poorly inside.
