Provided temps will be in high 80's or warmer you would be ok. Those conditions seems unlikely in Michigan so I recommend keeping them sheltered.

I would recommend repotting these cuttings and potting in good draining soil, plenty of perlite mixed with cactus soil and some good quality potting soil ammended with slow release fertilizer until more established. 1/3, 1/3, 1/3. Don't over water, let your leaves be your guide. Pot up til there's about a 2" gap between rim and soil level. The soil levels on these look a tad shallow. Ave 6 hours morning sun.

The one in the blue pot has inflos so is going to bloom for me!! That is the reason I have not repotted, this is how I purchased it!

Now is a good time to repot the other one?

Great, inflos, yay! And I'd say after it's done gifting you with blooms, to go ahead and repot then.
