When you take plants outside after being inside all winter, they will need to be gradually adjusted to full sun. I don't know that your warm season is long enough to do that for some plants. I'd be hesitant about putting D. marginata in that much sun even that far north. I don't do that here in AL, and never did in OH either.
Tropical trees can definitely handle full sun, once acclimated to it gradually if one's season is long enough, but most other tropical plants are from the jungle floor, where they would never get any direct sun. At much higher latitudes like where you are, the rays can be weak enough that some of them appreciate it, but please be careful about letting plants get sunburned. It happens to a lot of mine each spring even though I think I'm putting them in shady enough spots at first. Some of them can take so long to recover their appearance that it's really worth avoiding. Even though my plants are only inside for 3-4 months for winter, that's long enough to eliminate any acclimation they might have had to significant direct sun when they were outside the previous year.
Not familiar with the first 2 mentioned to have any specific feedback.
