It looks like the weedy amaranthus that popped up in my yard....everywhere! Get rid of it before it goes to seed.

lily is a bulb ... you might get info in that forum.. if its active .... it has a dormancy period ... and i am pretty sure.. a requisite cold dormancy ... it should have been properly planted in about october or so ... so .. as a bulb.. it could have done its fall root growing thing ... if your soil is still workable.. plant them . one thing for sure.. it doesnt need to be sodden.. all winter long .... that is not good for bulbs ..... if not.. out into the garage ... and put an ice cube on them once in a while.. just so the media doesnt get bone dry ... its a trick to not overwatering with a watering can.. in winter .... or take them back.. and tell them they are not houseplants ... ken

Looks like it might be Sisyrinchium californicum (yellow-eyed grass). Thats a native on the west coast, but I have really never encountered it. George

Hi & Welcome, On the left is a nice Kalanchoe Beharensis Fang it seems. The other I don't know, maybe some Echeveria but it needs more light. Yes, one can use a leaf to start a new plant w/ this Kalanchoe. For a Jade you can use a cutting or a single leaf. I'd concentrate on learning how to grow these first. Then after a while one can start to play w/ cuttings. Sorry, don't mean to be vague, but the frequency of watering will depend on several factors: the kind of mix you pot them in & the setting in which you grow them. But since you said you're new to succulents, broadly speaking about succulents & their watering, we often suggest: when in doubt about watering, don't.
