It would be helpful if you would post pictures of your plants, and more information about your situation-where you live, what your typical winter and summer weather is like, etc. Different plants have different requirements, and a general answer may not work for all of your plants.

Here is a picture. I should have thought of that earlier! They are still in their original pots, arrived through mail and it looks like they had a bumpy ride here. I live in Michigan and we get cold winters with lots of snow. Temps maybe go down to -10F at most. Summers are quite warm and humid with temps reaching high 80s to low 90s or so. I don't know the names of any of these.

These will not survive a winter in zone 6. You can put them outside for the summer, but if you want to keep them past that, you will need to bring inside before the first frost.

What a fabulous present, mkpearse. Would you be able to post a clearer picture so people can identify them?

yes, here are few photos I just took. I'm waiting for the weekend to get some pots and transfer them.

Lucky i wished i had that much

Nice collection, and if taken care of they should grow really good for you. I don't see any that would overwinter outdoors in your zone.
The garage is probably too cold too, unless temps in there don't drop below about 40F or so - few may need little more than that.
Just in case they were kept indoors for a while, make sure you don't put them in strong sunlight immediately, they need to acclimatize - get used to stronger light. But the fresh air and eventually more sun would be very beneficial.
It seems to me the soil contains lots of peat, so double check (it is quite difficult to keep proper moisture with peat). Grittier mix would be better in my opinion.

I see few echeverias, I think there is aeonium there, few haworthias and some crassulas - hopefully they get ID-ed for you by someone better than me.
