I highly encourage keeping them outside over the summer. Could you rig a sort of shelter over them to keep the rain off? I use one of those mini greenhouses just so I won't have to bring all the plants inside (especially the delicate ones) whenever it rains.

Your second plant is a Sempervivum. They are very hardy, so you could keep this one out all year round. They do the best outside.

Just to add to what mesembs said, the last one is an Aeonium, which in warm weather goes dormant. Leaves dry and drop off. If you get warm weather in your location, that might happen. Do not water Aeoniums much in extremes of temperature.

Even better - consider potting them into very well draining mix - one that contains hardly any soil, and lots of coarse perlite or pumice, and grit. There will be less concern about rain, unless it is torrential rainstorm, and lasts for days on end - in that case, putting a plastic sheet over the plants, or even just garden umbrella works. In worse case, they can be brought inside if you have just few plants.

Semps will grow great outdoors year round and look best; could be in a container or ground. Just make sure there is good drainage - as for all succulents :)

If taking any plants that were indoors outside for the first time, make sure they get acclimatized to outdoor light....
