As with most of the epiphytic/'jungle' cacti, they are relatively easy. Good hanging plants; keep slightly moist in the growing season, and let it dry out more in the Winter. Should have a well-draining mix as with all cacti. Propagated easily by leaf cuttings in sandy soil.

Hoya carnosa - Plant Finder - Winter hardy to USDA Zones 10-12. In St. Louis, wax plant is easily grown as a houseplant. It is best grown in a standard, loamy, well-drained potting mix. It may be trained to a small trellis or framework. Site in bright light with at least 1/2 day of direct sun. Tolerant of curtain-filtered sun and bright indirect light. Good light is necessary for flower production. Pots should not be rotated or moved to another location after flower buds appear. Water plants moderately but consistently throughout the growing season, allowing the soils to become nearly dry between water applications. In winter, plants require less bright light, less watering and tolerate night temperatures to 50F degrees. Do not remove the flowering stalk after bloom because new flowers will form on the old spur.

Schefflera.

Several names were suggested. Ficus does not seem to fit, and with the benefit of the new pics, the stems do not look thick enough to be a Peperomia. That seems to leave Ardisia. Have you compared your plant to Ardisia humilis and elliptica? https://garden.org/plants/view/71554/Shoebutton-Ardisia-Ardisia-elliptica/ https://inaturalist.ca/taxa/158587-Ardisia-elliptica https://garden.org/plants/view/361548/Coralberry-Ardisia-humilis/ https://inaturalist.ca/taxa/427934-Ardisia-humilis
