Fruit tree placement for zone 7b

Hi all, I'm working on starting my site in zone 7b. I'm looking for plant suggestions and placement. I currently have 2 spots where I am considering hooking up drip irrigation, I did 2 sprinkler heads last year for my vegetables and it seemed to work alright besides the sprinklers needing repairing at the end of the season. I just recently purchased 3 paw paw seedlings, I also have an appletree, strawberries,blueberries, an established 30+ foot long grapevine, groundcherries and huckleberries that I am looking to improve on. I have limited space it seems and I would just like any input on how to use it the best. The sun will rise across the street and set behind the pond on the right.

Hey - just wanted to let you know that Malwarebytes, one of the many anti-bad-stuff programs available, is blocking the site where you uploaded your photo, presumably because it harbors spyware.

Pawpaw trees are an understory tree so the best place for them will be between the green roofed house and the edge of the (woods?) near the pond. This will give them the needed shade while they grow then they will get enough sun when they can make use of it.

The next step would be to actually mark in a sun track for winter sun and summer sun so you know where the blueberry and apple tree will get the necessary shade and sun as needed (most tall bush blueberries can take some afternoon shade where the apple will want full sun all day long).
