Hello lottierifah, the glass containers do look nice, but as a rule for me, I never plant any of my succulents in a container without any drainage holes.
You got a mixed bag of succulents there. With varying growing/watering needs. I think your Kalanchoe is acclimating to the new set-up, but it does prefer more light to perk up much nicely. I would really recommend though that you move the plant to its separate container. In time, that particular plant will start making new babies at the edge of the leaves, and you will just be overwhelmed by how many it makes, and can easily overrun the other succulents.
Looking at your other plants, like your cacti. Most cacti go dormant during the colder season, so it does not need much watering at all. It prefers more light and more sun, compared to the other succulents growing with it.
The one that has yellow and red cacti, that is a desert cacti that has no chlorphyll, so it has been grafted to a tropical cacti which needs more moisture, and that is what helps sustain that colorful desert cacti. So you see the conundrum there, it is really hard to keep them together alive, they have varying watering and lighting needs. You can still grow them, in their own container, but be ready to accept the reality it is not the best combination to do. Some merchants/growers just like to do that, it does look attractive, but in the end, not sustainable in the long run.
The one that grows like a rosette, looks like an echeveria. I prefer to keep that type of plant in its own container too, or you may grow it in much wider, but shallow container with drainage holes together with the haworthia (plant in between the two cacti).
Grouping succulents is nice, but group them according to their growing needs, to make them last longer and use containers with drainage holes.
