So just wondering what this is. It had more leaves that fell off. Is it dead?

Hi & welcome! Do you have a pic of when it had more foliage?

No I don't unfortunately

Let's assume a positive attitude then & look forward to being able to recognize it in the future as it makes some kind of new foliage. :+) Do the leaves feel succulent? If so, probably a member of Crassulaceae family but I don't feel any more specific vibes than that. Maybe add a pic of what's left of the better looking leaf on the L?

Why do you suspect it's unhappy? Too dry, wet, hot, cold, got dropped, bitten, forgotten...? How long have you had it? Hard to say what kind of change might help encourage more signs of life, from just the pic.

Here is a pic of the one my mom has with foliage

The one I have, all of the leaves have fallen off but those two and they are dying. It hasn't been in much sun at all. I've had it since middle of May. Leaves free some but then started to fall off. Just want to know how to take care of it and if it will grow any more.

The bigger plant looks like maybe an Echeveria, growing in low light... rosettes would be more compact and leaves probably a pinkish hue in the sun, if my guess is right. These plants like strong light indoors, like hours of daily sun.

The plant in the OP looks like a goner to me, but I've been wrong about that plenty of times. In doing a postmortem you should try to figure out what went wrong, and what kind of changes you can make to care to maybe improve your odds in the future. What kind of soil was it in? How much light and water did it get? Were there any insects in the rosette that you could see (like little white or black dots)?

It should be possible to propagate this plant from a leaf, if you want to try an experiment without damaging the mother plant too much. All you need to do there is carefully detach an entire leaf (the base has to be intact). Lay the leaf on top of well draining soil in bright shade, and water the soil when it dries out at depth. Eventually it will put down roots and sprout a tiny new rosette, using the stored up energy and water in the leaf to keep growing and make more roots until it becomes independent.

I think the biggest problem was sunlight. I didn't know anything about succulents. I started with these out on the porch. Then the temps got really high outside and leaves were turning brown so I though direct sunlight must not be good. So then I brought it inside and put it in the window and it seemed to do great. I think the leaves started falling off and I moved it to an area without any light. As it started dying I started neglecting it. Sort of giving up on it. So lack or water and sunlight probably caused the damage. I think maybe it is a echeveria ruffled .. I don't want to break off last leaves to see if it will root. In scared it would just be destroyed then I'm left with nothing.
