The middle one is elephant grass, but that's the only one I know.

The top one could be Echeveria agavoides "Lipstick". Yours may develop the red edges later on (possibly with more sun). Here's a link to a page that shows what I think is your plant. http://succulentsus.com/echeveria.html

Scroll down the page until you see it. Good luck.

I am not sure about the name 'elephant grass', but plant #2 looks like Portulacaria afra (aka elephant food or elephant bush - that's probably what cdestiny meant; and few other common names.

Agree with Sylvia about #1 being Echeveria agavoides - there are few varieties and cultivars; and #3 seems to be peperomia. Not sure which one.

Yeah elephant bush is what I meant to say. Don't know why I always tend to say grass...

cd

np...maybe another 'common name', lol.

I suspect the 3rd plant which looks viny is Hoya recovata.

The flower stalks look like peperomia, as Rina said.
