I'm sorry your little Caboose had a night fright.
From the first photo I can tell you that your boy has lost a couple of his primary flight feathers (the right wing on the first pic).
Both wings look good and don't at all seem to be broken nor dislocated.
Due to the missing feathers on one of the wings there is currently a slight imbalance and this can be noticeable when flying.
It will take him a while to get used to this and in a just a few weeks' time he will grow back the missing flight feathers.
He is likely still a bit shaken up and stressed from the night fright and you can try and make him more comfortable by covering his cage on three sides and having some soothing music on for him.
During a night fright budgies can lose some feathers, these are mainly the primary flight feathers on the wings and the main (biggest) tail feathers.
In more than one occasion I have had a budgie to lose a few flight feathers and I have also noticed sometimes they will vibrate the wing which was affected during the night fright. They feel a bit of discomfort at first, but will soon adjust to this and the wing shaking/vibrating will stop.
Under different circumstances, budgies can also vibrate their wings when they are excited/happy.
I hope your Caboose will soon start to feel better.
