Yes, Welcome to the forum. Those are quite a few to go through for ID. Just have a few minutes jumping in & out of the forum, so quick thoughts on some. 2. Does look like Haworthia cuspidata. 4. A. Is Aloe variegata on the right track with Haworthia pumila for 5. A & B. C. has been see listed by a couple of cultivar names, one being H. attenuata 'Wide Band' or 'Wide Zebra'. Nice Gloxinia! Just so you know, when writing plant names, single quotes are used on cultivar names. Species names are not capitalized. Common names or nicknames can use double quotes (but are not necessary). I believe all Bryophyllum have been moved back into Kalanchoe now. Cute pups, all! The Gasteria & Sans would require lengthy research. Sorry, I've no time for that now. Maybe I'll get back.

Your Hens and chicks looks like Sempervivum 'Red Beauty'. Just in case you don't know, most Sempervivums need to be out in the cold in the winter so it doesn't make a great houseplant. A better garden plant for sure. i can't identify the so called zygo cactus from your picture. Maybe a closer shot? The third picture looks to be a sedum of some sort. These all look to be succulents, not cactus, to me. One last thing, most succulents are poisonous to cats so I don't recommend you let your cat eat any of them.

Sadly, just because a bagged soil is called 'cactus soil' that doesn't necessarily mean it's any good for cacti and succulents as we've said many times before, it's just sales blurb. They will die in that mix whatever their size, large or small, the result will be the same. Can't tell what the planter/s look like size wise in relation to the plants or whether it's one big planter, but whichever, there's way too much unused 'peaty' type compost. It will cause one of two things to happen...if you water thoroughly which they will need (but they also need to drain properly) it will stay wet and they'll rot. Failing that, the soil may become hydrophobic, you will think you are watering it but it will stay dry at the roots, as spray bottles don't water efficiently. Please do a search for a more suitable mix using the search box a the top, your plants will thank you in the end. Gill

Chris Yes, pls. number them, take individual photos, or at least just 2-3 per photo. And try to get more of close-ups, some are very small to ID. Succulents need very similar care: fast draining potting mix, containers with drainage holes (hope all of yours have it), very good light - many will do best in good sunlight. And letting us know your general location or at least a growing zone would help. Best if added to your name.
