Hi anonymousjustrandomqns.
It sounds like you're seeing pending purchases and you want to know if you'll be billed again, correct? We'd like to help any way we can.
Just to confirm, are those charges still showing as pending if you view your purchase history at this time? See your purchase history for the App Store, iTunes Store, and more
Were the purchases you made for more than the amount of your Apple ID balance? If your Apple ID balance wasn't enough to cover the full amount of your purchase, Apple will attempt to charge your primary payment method, which could be related to the pending charges you mentioned.
You can find more information about how Apple ID balance is used, and how charges are billed here: How apps, content and subscriptions from Apple are billed
For more information on checking your Apple ID balance, please see this page: Check your Apple ID balance
Take care!
