Bryophyllum verticillatum aka K. delagoensis is a weed in most succulent collections. Best removed.

Hardy from about Z9+. In colder zones, it's a fascinating novelty prized for its' blooms.

I just don't know if I should keep it in direct sunlight, partial sunlight, water often or not so much. Any advice is much appreciated.

It's also in quite a small pot, should I move it into the large pot it's sitting on? Is that a risky move?

I just have no sense as far as gardening and I'd like to keep this assortment alive as long as possible.

Try posting this on the Cacti and Succulents forum for some very specific ID and care advice. There is quite an assortment in that container and it looks as though some replanting or division is in order. Most want a very fast draining potting soil, as much sun as possible (full, all day) and minimal water. And winter protection in most zones lower than 9.

The plants look like they've been getting at least 2-3 hours of direct light in the adjacent past.

The red one: Crassula capitella 'Campfire'. In the last picture, the grey one: Graptopetalum paraguayense.
