My phone tells me I have too many apple ids how do I erase so I can use I cloud again

Are you trying to login to iCloud when you do this? If so, are you using an existing AppleID that already has an associated iCloud account?

Each iOS device can only create three new iCloud accounts in its entire lifetime (regardless of changes of ownership). So if creating a new iCloud account and AppleID, or using an AppleID that has never signed into iCloud before, you may get a warning that the lifetime limits in new account creations has been reached. In that case, you need to find another Apple device to make the iCloud account on.

The restriction has nothing to do with how many existing iCloud accounts can be used with a device. It simply limits the number of new iCloud accounts that can be created with that device.

When does the phone tell you so? Do you have a screenshot or maybe a photo?
