This is all I've got. I do not think it is String of Nickels. Can anyone identify what it is ?
This looks like a Kalanchoe. Unfortunately that doesn't narrow it down much, because there are 125 species of Kalanchoe. Many of them are common as houseplants.
It looks similar to this unidentified Kalanchoe from the Epic Gardening article, "How to Propagate Kalanchoe". This one appears to have an upright growth form, more shrub-like than vine-like.
Or it could be Kalenchoe uniflora, as seen in a screenshot from the Youtube video, Kalanchoe uniflora Houseplant Care.
Here's a cultivar of Kalenchoe uniflora, 'Freedom Bells' from Dave's Garden
None of those options has the all-over reddish tint that your plant has. But your plant looks pretty unhappy and stressed, and some plants develop a red tint when they're unhappy. If you can get your plant in better health, its color may change a bit. Or the red color could be due to sun exposure - essentially the plant equivalent of a tan, and not necessarily a problem. Kalanchoes can handle full sun. Either way, your plant would probably appreciate some better soil. As with all succulents, make sure the potting mix drains well, and let it dry out between waterings. The easiest way to kill a succulent is to keep its potting mix wet all the time. Here's another Kalanchoe care guide.
FYI, according to VetMeds.com, Kalanchoes are poisonous to pets, so if you have a free-roaming pet, be sure to keep this plant out of their reach.
