Tropicals are way out of my area in all senses but might it be a Polyscias? P fruticosa perhaps?

Water thoroughly when dry. Let water run out the bottom holes. Never by tablespoons. You can tell when they need water by inserting a wooden skewer for a few minutes. When you remove it, if it’s damp, don’t water. As for the third pic, I suspect the pot is too big for them, and they should be potted a little higher if you are able to repot in a smaller container. The recommended soil mix here is commercial cactus and succulent potting mix combined 50-50 with perlite available from your nursery. You are on a good start with your succulents. I suggest you take time to read many other threads here, and you will learn a lot. Also there are some good YouTube videos. I like Debra Baldwin, another is Sunshine and Succulents.

Thank you, Ken. In NY, my Chnese Evergreen was on top of a wall unit, on the corner closest to the window. I watered weekly in summer (feeding every 2 months) and 2x month Sept-Apr. I keep these in the gallery/atrium, which is a 2nd floor open air garden with the walls of a 3rd floor above it. There it receives all day bright light but little to no direct sunlight. I have these in the same high drainage soil I use for my bromeliads, hoyas, terrestrial orchids, adeniums, and plumeria, so it’s fine under the rains. Of course, I’ll feed these monthly at 1/2 strength. Our area has very high humidity and it seems to love just where I have it ... It’s grown tremendously in one month.

Cedar, or Eastern Red Cedar is the common name for this tree whether anyone likes it or not. There are many more than one type of Juniper, and to call all of them Juniper and not differentiate between them is ridiculous and confusing, Yes, I know it's a Juniper, but like most people I'm just an average person, not a botanist. and I'm not that picky about using botanical names. Try Googling "Eastern Red Cedar" and see what happens, and then Google "Juniper". Still confused ?
