Not sure about #1.

#2 Croton/Codiaeum.
Needs good bright light to keep the colors constant and bright, otherwise the leaves can go mostley green.

#3 Sansevieria.
Bright indirect light will keep it happy. Sudden direct sun can burn the leaves.

#4 Rhipsalis maybe?
It looks similar to Hoya linearis which I have, but I don't think that's it.

#2 is a Croton, lost its color due to not enough bright sun.

#3 is a Sansevieria of some kind (a snake plant), I'd move it out of direct sun, best for now into partial shade, see if that darkening is sunburn or other damage.

#1 looks like Kalanchoe fedtschenkoi

# 2 & 3 - I agree with the others

#4 - I know it as Hatiora salicornoides, but I think it is now called a Rhipsalis.

#4 is not Hatiora salicornoides, Hatiora salicornoides has segments that look like bottles. It is a Rhipsalis, but it would be hard to tell which until it blooms. The Sansevieria looks like it's rotted. I'd take it out of it's pot and give it a well draining soil. Al's soil would be wonderful if you added some crushed granite to it.

#4 is a euphorbia, dont know the proper name for it but also called a pencil cactus

#4 is not a pencil cactus euphorbia either. It is a Rhipsalis/Hatioria, just not salicornoides. You won't know which until it blooms. There are over 20 different species that look like that. I'd give it some better draining soil and a much smaller pot. Treat it like you would an orchid. Feed it an acid fertilizer diluted 1/4 strength every other week. You can attempt to keep it more bushy, but it will eventually want to trail down to a few yards if you let it.

Mentha is correct. Euphorbia tirucalli ("pencil cactus") is a much bigger plant (both in overall size and stem diameter) and grows upright instead of trailing. Also it's not segmented like the plant in the photo.

You are right, I took another look at the photo and it is not the Hatiora saliconoides as I first thought.

What about an Erythrhorhipsalis? (I think that is how it is spelled.)

I thought this site was for everyone, novices alike, when some of you people give your responses you dont have to be so rude because you know all the answers..some of us dont have a degree in horticulture or botany and we dont know proper names of our plants, but we love plants, so pls dont take the enjoyment of this site away from people like myself who arent experts

Hello

Thank you for the help in ID my plants!

#1 plant has never flowered. I've had it for at least 15 years.

I agree, I am new to this site, and have read some pretty rude things, those ppl should remember the days when they were just beginning. I have lots of books and have dabbled in houseplants since I was a kid (28 now) and I come across many plants I don't know what they are or just can't find them.

Nothing rude has been said in this thread.

1) Kalanchoe
2) Croton
3) Sansevieria
4) Rhipsalis "Trails"
