A 110ltr tank isn't big enough for 5 angels, I would just go with the tetras with that tank size.
Corys will be fine and I wouldn't feed more than twice a day because they probably wouldn't eat all of the food leading to a build up of decaying matter.
Angels do become quite aggressive, I have kept them successfully in the past with a shoal of neons, but that was in a 700litre tank.
Also if you find a breeding pair they will become aggressive between eachother, they are in the cichlid family so are great parents.
