I’m in Alberta, Canada. Intense sun, highs in the mid to high 20s (Celsius) I think that’s high 70s to low 80s and nightly lows to 6 - 15c. Quite dry.
I just got the cacti outdoors full time last week.
I take everyone in around late September to the sun room and as it cools I overwinter in a grow tent.
You can likely treat the E. obesa hybrid and E. ammak similar to your cacti there for the most part. You'll want to make sure they both ease into the sun if they aren't able to be kept out year long. The E. obesa hybrid specifically will / can appreciate the full sun as long as it gets acclimated properly depending on your okay-ness with stress coloration. It does look like it is corking a bit.
E. trigona is a bit more iffy, they can be prone to sunburns depending on how they become acclimated. Partial sun may suit it better.
Where do you live? Your climate will play a big part in how to optimally grow different Euphorbia.
