How can I make a new Apple ID if I already exceeded the limit?

You will have to create one on another device then log into it on your iPhone.

You can create an Apple ID here→https://appleid.apple.com/account

Then log into it to your phone, as deggie says.

Why are you creating multiple IDs; this is recipe for software and synchonisation issues across your devices

Your Apple ID should be unique and SINGULAR .

There is NO benefit and only problems to multiple IDs

The ONLY TIME YOU SHOULD seek a replacement is if your iCloud account is somehow hacked - I say that because the cloud service within a web browser are the weakest link in Apple Services .

You're devices however have an extremely low risk of direct hacking success.

Again what are you trying to do with multiple accounts.
