All should do OK except the single leaves. The yellow one almost for sure won't make it and the one you pictured alone isn't a clean removal from the stem.

Hello :) Thank you for your answer :)

And for the "yellow" one, actually it's not yellow it's pink ^^ bad lighting sorry

and for the other one, do you think I should ask for the whole "flower" instead of just a leave ?

I am not sure if you mentioned soil you have - what is it? It would be better to start them right - you have few nice cuttings, if you can put them into suitable potting mix, they have better chance to survive. If you have only peat, or only garden soil - these are not really suitable for succulents.
You mentioned you are new to growing succulents - make it easier on yourself & pot them into well draining soil. That's one less thing to worry about to begin with. It is extremely easy for anyone to overwater in water-retentive soil...just my opinion.

Thank you for your answers Rina :)

I will get some perlite soon, but, for the succulents that I already propagated, I has worked just fine, except for the bug thing that happened, but I do not over water them, I only spray water on them and wait for the soil to dry completely before spraying again, but as I said I will get perlite and mix it with the soil I already have, and do everything right, but until then, I don't want to loose those cuts that i've got :)

Thank you for your detailed answer and for the pictures as well, but I would like to tell you, that the one that I propagated didn't look like that one at all ! And it still worked, but the leaves are a lot thicker than the leaf pictured alone, and I don't think it will work as you said.

And please why did you say that the yellow one wouldn't work (it's pink by the way) ?

The one that looks "yellowish" in your pic, looks like its on the softer side meaning not viable. Soft leaves never propogate because they are already rotting. If its just your camera dont worry about it, but it does look like its soft. Other times a leave is older and ready to fall off to make way for new growth, so the plant stops giving that leave nurishment to focus on newer growth, and sheds it, but by the time it comes off (or is ready to come off) its too far gone for propagation. Please, Howard and Rina, if i did not explain this right, correct me. Thanks :)

Okaaaay I think I get it !! But you have to know that the whole plant looked pink, some leaves had a more greenish color, but overall they were all the same color, and they did not detach easily, if that changes anything :)
I will still try to put it in the "nursery", to see what happens. But thank you so much for your answer !

Little update : Are those dry enough to be planted yet ?

And here is another picture of the pink leaves with better lighting

Thank you SO MUCH for your help !!

Those are already dehydrating (wrinkles) and probably won't do much... doesn't hurt to try.

I don't understand, I got them about two days ago, and it's not like I put them in direct sun or anything :/
But I'm going to try anyways, Thank you !! :D

Leaves located on the lower region of the plant will naturally eventually kind of wrinkle up and fall off. That's normal, of course. So when you pick leaves to try to root--and I know I choose from the bottom too--you have to learn to tell which leaves are still healthy and which ones are on their way out. The yellow leaves, yes, are wrinkling/dehydrating and were perhaps already on that path, so I also feel they will not have the energy to root. You have to pick really solid, healthy leaves. You'll get better at telling the difference over time. Good luck. Everything else, I'd say go for it.

Update : Almost all of them made it!!!! Apart from green one pictured alone :) but it's ok because I will find a way to make it work maybe take a bigger part of the plant or something. (Even the yellow/pink leaves made it!!)
