Hi Pepper... you came to the right place. We all also fell in love with semps... it's so easy to do.
However, semps do really like to be outdoors. They would be most healthy that way and even appreciate freezing in the winter. But I think you
can grow them indoors but I don't know much about that. Although they will certainly not be at their best.
Your last picture I agree is an Echeveria, not a sempervivum. Completely different. It would die in freezing temperatures. You might have better luck with those indoors. The good news is that there is a large variety of colors and forms to choose from. You might try another forum in this web site:
