Give it some time, they look well on their way to being up. Chance took what seemed like forever for both to go up and stay up! (The tops tended to tip like your pups) I think he was about 10 months old when they finally stayed up.
Though Bo Ann may need her ears glued/taped since they're more down than the OP's.
Be sure to offer plenty of things to chew on to help strengthen them!
They should be fine. Nala is 8 1/2months and her ears are finally just standing part of the day so I am keeping my fingers crossed as they never stood at all. But as someone said, if they stood before they will again. Make sure she has plenty of bully sticks or antlers to chew on.
