IMO, they are all hardy succulents.

If you don't mind me saying - do you think it is easier to ID plants when the photo is blurry?... When looking for ID, clear photos are important, sometimes few shots of the same plants and if few, pls. number them so it is easier to refer to.

Better pictures:

I think this one is a dragon blood sedum?

1)

2 &3) More sedums?

4) Some sort of Sempervivum?

#1 - Sedum spurium 'Dragon's blood' ('Woodoo' is very similar)

#2 - likely Sedum reflexum 'Blue spruce'

#3 - not sure, could be Sedum tetractinum 'Coral reef'

#4 - Sempervivum arachnoideum - these are monocarpic; blooming rosette will die after flowers are finished

They are all hardy and better if grown outdoors year-round. They won't look that great indoors.

Thanks, Rina! I will resist the urge to bring them inside and will replant S. spurium in the ground. I'm just afraid of losing them

In your zone, it should be np. I grow them all (and some others) in colder zone without problems. They could be in containers or ground, but good drainage is essential. Wet feet will kill them...Spurium looks also nice in containers either hanging or raised, as it will hang down and cover it all - or just use as ground cover.
