These are the last of my un-named plants and they're just too difficult for me.

1) Thought this was 'Mother of Thousdands' but I was recently wrong about one and started to doubt myself as there are 3 or 4 that look the exact same to me. This one is in the ground outside and have no idea where it came from as there are no others around.

2) This one I had labeled as Echeveria 'Curly Locks' but it doesn't look like any of the others. Also is it normal for these to continually lose their lower leaves? Also can get a picture of the "flowers" if that will help, or infloresence I believe they're called?

3) Last one. Kind of thought this looked like Haworthia cymbiformis but the babies don't look right for it.

Thank you for any help, it's much appreciated.
