everything is looking good! I want to try some of your blueberries, I have raspberries to trade . I wouldn't mind trying a paw paw either. Never had them before, they are not a normal thing in our grocery stores, though i thought that with dragon fruit and one of my local places started selling it so maybe now that i mentioned it they will sell some of these!
You can grow blueberries in your zone. They just need sunlight most of the day. You could build a whole hedge full of them !! I can't grow raspberries here because it's too hot but blackberries love it here. I have the thornless ones but brambles grow wild everywhere so blackberries are good to grow here and in your zone.
