The South Hogwarts Region Balloons in Hogwarts Legacy are grouped in 5 sets of 5 pieces each, and you need to pop all of them if you aim for 100% completion of this area. The only requirement to unlock this type of collectible is to own a flying Broom, which you can do after completing the Flying Class main quest.
Then, all you need to do is locate the hidden Balloons and pop them by flying through them on your Broom. If you pop multiple sets of Balloons, you unlock Broom skins, which can be claimed from the Exploration tab of the Challenges menu.
Where To Find the Five South Hogwarts Region Balloon Sets in Hogwarts Legacy

Balloon Set #1: Southwest of Hogwarts Castle
The first South Hogwarts Region Balloon set is found southwest of Hogwarts Castle, at the location marked on the map above. Once in the right spot, fly high on your Broom to spot the five Balloons, then go through each one to get credit for the collectible.
