It is Kalanchoe delagoensis. Many consider these weeds. I happen to like them (but you have to be vigilant about picking up the baby plantlets that fall from the leaf edges (starting new plants). This one may not look good right now, but it is a survivor. It can grow in just about ANY conditions...including from a crack in the cement, a piece of your carpet, an empty pot, etc. :D You have been warned. The flowers are very pretty. :) I take it back...if you have SNOW or freezing temps...it would probably not survive that. Anything else...it's A-Ok.

is the succulent forum dead also ... can we have some focus.. before we start arguing if its a jade plant.. or a....a....a.... carp.. whats the one i always forget about that looks like a jade.. lol .. kalanchoe... lol.. knew if i typed long enough i might get there. .. soil looks old and mucky for either ... probably sun starved also ... ken

The top left looks like an Echeveria, and I think the one next to it is too, but I'm not sure. They all need well-draining soil and, if you're growing them indoors, you should probably put them in a south facing windowsill for maximum light. The potting medium should be mostly grainy, like perlite or pumice, no peat moss. Perlite is that white rock that looks like little pieces of styrofoam. I'm not sure about the other ones, but hopefully someone more experienced than me can help you. Good luck!

1. Looks like Crassula ovata aka: Jade. I also see Senecio jacobsenii for some reason. Could you take it out of the pot and take another pic:)? 2. Mammillaria what species I gave no clue. For some reason when it comes to finding the species of a Mammillaria I have zero patience;). 3. Can't really tell. Pretty young still. Maybe a Trichocereus:). 4. Looks like Opuntia monacantha monstrose:). For all your plants it's pretty much the same. Use a gritty mix since it's so rainy where you live. I would use a mix with zero organic material. Keeping in a greenhouse would be good. Make sure there is good airflow in the greenhouse:). If you are able to keep dry I would water them once every 2 weeks. The jade looking plant maybe once a week. If any of the plants are in lots of humidity you may have to adjust. Make sure the mix is dry before you water again. Check almost all the way to the bottom of the pot. Not just the top layer. You can use a little wooden skewer. Push the skewer down to the bottom and let sit for a min. When you bring it up and the wood is damp. No need to water:). Goodluck:) Oh ya make sure the pots have drainage holes:).
