The hitchhiker on the left looks like it could be Kalanchoe marnieriana & the one on the right, possibly a Huernia. You might need to wait for a bloom to get the species name.

Thank you, Rosemarie!

Rosemarie,what is the name of the main plant?? I love that one.
Thanks Kathi

Do you mean the ground cover around the volunteers? It is a stonecrop called Sedum rupestre "Angelina." At least that what the tag says.

Crenda,

Disagreeing with RoRo is fraught with peril, and I'm almost always wrong, but might that one on the left be a Cotyledon? Ro, how is it a Kalanchoe to you?

Good questions, Jeff! =) Made me stop in my tracks.

Now, how do I explain how I came to this conclusion?
First, there is the size consideration. Knowing the size of the Sedum & comparing to the leaf size of the one I consider Kalanchoe. The opacity of the leaf (see-through-ness) says Kal to me, as I think most Cot are not. Also looking thin, compared to thick Cotyledons. The leaf suggests slightly scalloped margins, like that of K. marnieriana. The red edge is slight, which I believe would be more pronounced on a Cotyledon (also, could be pinched & pointed). There aren't too many Cotyledons that look like this (all things considered).

But, as always, I could be wrong! So, I suppose I should've said wait till it grows out some & when it blooms, its ID would be clearer. =)

Here's a closer picture after I repotted, so you can see the whole plant better. Either will do well in gritty mix, yes?

Thanks for the additional pic, Crenda. This shows the petiole attachment to the stem, as well as the off-to-each-side (? can't think of good wording) placement (both consistent w/K. marnieriana), rather than opposite, like a Cotyledon.

Most times the leaves would be more upright, as in the pic in the link below.

Thank you both. I realize it is a little thing, just under 4 inches tall. I just wanted to be sure I have the right soil and light for it to thrive.

BTW - the other guy initiated me with a few good jabs to the fingers! Why didn't I wear my gloves?
