Welcome, and you are in the right forum :)

1st one is Kalanchoe blossfeldiana - did it ever bloomed? It seems to be very long, it could be pruned to be shorter if you wish and clippings can be rooted into new plants.

2nd looks like peperomia to me.

Wow, that's great! When I google Kalanchoe blossfeldiana I just see a ton of flowers, and much more bunched-up leaves, so I initially passed over that option. I've never seen it in bloom, but I could ask the previous owner. And peperomia definitely looks right for plant #2. Thanks so much for your help!

Kalanchoes bloom in many colors, flowers last a while but they doesn't bloom all the time. You can see them a lot around Christmas time; they are usually small and compact plants with lots of buds and/or blooms. They have tendency to grow leggy with woody stems as they get older. I had one few years ago that grew into a bush 2' tall from the soil line and almost as wide. It didn't bloom as much at that time.

Your plant probably did not receive as much light since the leaves are spaced more than what you see in the photos.

Here is a woody stem I had potted up and next photo is the plant it grew into:

Here is the another plant: all the leggy growth was pruned, cuttings potted up and now they are nice and compact plants:

That's so helpful, thank you! I'm going to try some cuttings from the Kalanchoe as soon as I get a chance. We haven't had much "weather permitting" around here lately, unfortunately, so I may have to wait for the sun to come back. Thanks again for all the advice, and the pictures too!
