I think what Howard meant to say was Gasteria, not gastric. I hope Howard doesn't mind, but I'm re-posting your pictures with numbers attached and using Howard's IDs and putting them with the numbers for you. #1. Haworthia something in the retusa family #2 & #3. jade x 2 #4 & #9. graptopetalum or graptoveria x 2 (okay, I forgot the second plant so #9 is out of place) #5. opuntia #6. gasteria #7. kalanchoe tomentosa #8. not a clue cactus Planto

I am assuming you bought the C&S soil from Amazon, so it is quite new. In that case, you can use it, adding lots of pumice. Many use it mixed 50/50. You could keep that decorative pot (cache pot) if you like it. The problem with those is that they fit (usually) very tight, not allowing any air circulation, sometimes creating sweating-too much humidity and moisture. But if you were to leave the inner (plastic) pot out of it for a day or two after watering, it may work. Make sure there is never any standing water in these cache (decorative) pots. If any of the pots are without drainage holes, either change them or drill some holes in them. Slots (if I am correct about what you call slots) are most likely not enough for good drainage. Your Mexican giant is apparently Echeveria colorata 'Mexican Giant' - it is supposedly slow grower. The powdery coating is most attractive (probably more than some other succulents), so just try not to touch new leaves much (not easy to do!) Difficult to say exactly why it is leaning: it may be that was 'squished' much in the box; it could have been growing that way since it was leaning towards the light source; the worse would be if the stem is rotting - you would probably already noticed. Make sure they are healthy, if any roots are damaged or rotting, they should be cut off. Prop it lightly with a bigger rock (similar to photo below) and make sure it gets good light - if needed, rotate the pot 1/4 turn every few days: Many succulents propagate from leaves easily - I have no idea about this one. You can try - & let us know...

Kara, Currently I leave both the plants at my east-facing window sill at which sunlight is available for around 8am to 10am. And I plan to increase the sunlight exposure by an hour a week. Hopefully, they can enjoy themselves =) P/s: I live in the southern region in which the weather is still sunny and not quite humid at this time of year ^^. Btw, being curious about location and some private information is welcoming here as it is part of our norms, so no worries :))) Frank, Wow, so this one is the hybrid between the Sedum and Echeveria? Patrick, Ok, so it should be fine to leave them there a week before watering again. I also wonder whether gradual sunlight adjustment like I plan is ok or it is too long? P/s: about the ID yeah we should wait for more comments to confirm. These echies are sometimes too shy to reveal their true forms, or they just love to make us confused xD Thank you all for being very informative and enthusiastic in supporting me ^^

Dont make mini gardens, the plants will not prosper. Youll find the rhipsalis and the faucaria problematic to grow together, because one is a moderate drinker, the other likes to stay heavily on the dry side. Haworthia likes moderate light, but little water,the kalanchoe you mentioned likes to roast in the sun. Same could be said for other plants, most dont work together. The only ones ive actually seen do that, are dracaenas... and most arent succulent. Grow lights will not provide sufficient light, and are only used for overwintering in the northern regions(and ive read arguments about those). Since this is at work, maybe wasting power could have repercussions, so i wouldnt try..... Your tray isnt even deep enough btw.....
