I would assume that Sarah, Azzi, and Serah are almost assured of starting roles. (Jana could possibly beat out Serah for the starting center position if she has a "redshirt sophomore" leap, but most likely Serah's experience and post moves will win her the job.)
I would say that KK has the inside track to be the starting PG, given her high assist numbers and defensive disruptiveness. But there are other contenders, and I would name Ashlynn and Morgan as possibilities (leaving Heckel out of the picture for now).
The 3 position is the one with the greatest uncertainty, since there is no obvious "shoo-in" candidate. The contenders are Caroline, Blanca, Morgan, and Allie. I don't think Ashlynn will (or should be asked to) play the 3. She is the obvious choice as Azzi's primary backup at the 2, and she will get plenty of minutes there.
If Caroline really is the "old Caroline", then she will be a near shoo-in for the 3 spot -- unless Blanca proves to be fantastic. Caroline knows the offensive and defensive systems better than anyone except the coaches, and that alone gives her an edge on Blanca, even if Blanca is really talented and motivated. But if Caroline is physically limited, then the position is a battle among Blanca, Morgan, and Allie, and I don't think any of them can be considered "pre-season favorite". The summer and fall practices will determine the outcome of that battle.
The depth chart behind Serah at the 5 is Jana / Gandy -- no mystery there. Jana will get plenty of minutes.
The depth chart behind Sarah at the 4 is Ice / Ayanna -- not much mystery there either. If Caroline is limited in minutes, she could back up this position also.
The depth chart behind Azzi at the 2 is Ashlynn / Allie. But Azzi and Ashlynn will get 90% to 100% of the minutes before garbage time.
The depth chart at PG is KK (probable starter) / Kelis / Ashlynn. If Kelis is "really really" good,she might get significant minutes as KK's backup.
I think the above statements can be made with a reasonable level of certainty. What is noted as uncertain above cannot be made certain until Geno and the coaches see how the summer and fall practices go.
