Hi Jookie, yep that is a Haworthia coarctata and Bev (webesemps) is right they like less light but also warm, whereas the semps (hens and chicks) like cold, I totally recommend separating them. The other plants looks like a graptopetelum, and that would do fine with the hawarthia! The first year I had semps I kept them all indoors and they did terribly, 2 things I did wrong; 1-tried keeping them warm like other succulents, and 2-watered them too much! If you keep them indoors make sure to keep them in a cold window or something, and cut way back on water!! Your hawarthia looks great by the way!!
I'm originally from Detroit and now live in Seattle, still consider myself to be a Michigander!
Also be prepared to get really really excited about these little hens and chicks plants, cause these people on here are totally obsessed, and its contagious!
