Your Hawaiian Plumeria cuttings will just sleep it off for now. Just be very patient. Before when I hide my Plumerias indoors during winter, I have to wait till outdoor overnight temps are at least 50F before I can bring it out. So it will be about late April to May. When temps are tolerable already, I have them positioned in part sun/shade outdoors to acclimate it slowly to outdoor conditions. Your cuttings will grow leaf claws first, but you have to wait till it actually is able to open up that claw to be fully sure the plant is awake, otherwise it is so vulnerable to black rot at the tips when it suddenly gets chilled and overwatered. Our temps are still fluctuating high and low too much during mid to late Spring, so as soon as conditions improve, you can reposition the plant to a more full sun area.
Ideally Plumerias love lots of full sun, high humidity and warm to hot temps. It will be a nice challenge for you! Took me 3 years to understand it and lots of failed attempts
Just some photos for you to help you understand:
Leaf claw stage, cutting is still not fully awake:
Leaves finally open, plant is now defintinely awake so you can do usual watering and fertilizer application. The hotter the temps the more frequent watering it likes. In my area we go extremely dry and into triple digit heat, so I have to water everyday here. It may be different in your area if you have more rains, so you have much better humidity levels than we do:
Make sure you make the media gritty, coarse and well draining. I use cacti mix, compost, lots of pumice, sometimes some chunky lava rock, clay rocks or if I have kanuma and akadama japanese soil I use that too. Then I top dress with chicken grit (insoluble crushed granite).
