Sure, you are free to upload as many classes as you want.
Anyway, it is better that you give priority to classes that do something innovative, as those classes have greater chances of getting more exposure and consequently attract more users that will help you rise in the ranking.
That is why there is also the innovation award, which aims to reward authors that add more value to the site by being the first to provide here solutions that others have not provided before.
As you know, besides recognition and evidence in the site, you can get even interesting prizes from sponsor companies.
