They won't "lose" the apps. Even if you sign in with a new ID the old apps will remain on a device unless you delete them or erase the device entirely.
Can You Transfer Purchases to Another Apple ID? The answer is that there is no way to transfer apps or any other purchases (movies, songs, games, books, etc) from one ID to another ID. Apple just does not allow it. Further, you cannot merge two or more Apple IDs into a single one.
If you create and use a wholly new (not amended) Apple ID, you won't be able to transfer anything you have purchased from the iTunes & App stores to the new ID, but you can transfer your iCloud data (calendars etc) with a little patience. iTunes & App Store.
Keep in mind that things like downloaded apps, purchases, iCloud data, etc are all linked to an Apple ID, so if you change an account you will not have access to the data from the other Apple ID / iCloud account.
If you got a new email address and you used your old email address as your Apple ID and iCloud ID, you can change the ID and keep all content and data. When you change your Apple ID, you will not lose any data.
Everything is tied to the AppleID... creating a new one means you must repurchase/download apps, books, music, etc under the new ID. Content cannot be transferred between IDs. Is it the same for iCloud?
In your Apple ID account settings, you see a list of apps that you use with Sign in with Apple. To view the information that you originally shared with an app, select any app in the list. You can also view a link to the app's Privacy Policy or Terms & Conditions.
You can create multiple Apple IDs, but it's best to stick with one account. If you want all of your Apple services to work properly and your devices to sync, you need to make sure to use the same Apple ID everywhere you sign in.
You can use one phone number per Apple ID. In some countries or regions, you can use your phone number as your Apple ID. Are you looking to use your phone number as an Apple ID?

If those apps were originally purchased with that other AppleID, then you cannot update them with your AppleID. You will need to delete them and purchase them with your own AppleID. Purchases are forever tied to the AppleID used at the time of original purchase and download.
An iPhone is meant to be a single Apple ID device. You can use one Apple ID for iCloud and another for Messages/FaceTime, but you can't use 2 Apple IDs for one sign in such as iCloud.
Here are some reasons why you should avoid Mirroring when using 2 iPhones with the same Apple ID: All the critical and sensitive information will be shared mutually between the two iPhones. The other iPhone user can access all the text messages, photos, and call logs. The other person can change the playlist.
Apps are locked to the Apple ID used to purchase/download them. Not sure exactly why you created a new Apple ID, but unless you use the old one, you will not be able to update those apps. The only way to fix it is to delete them and then download again. Apps are locked to the Apple ID used to purchase/download them.
Apple allows you to sign up for a new Apple ID using any of your existing email addresses from services like Gmail, Yahoo, Outlook, etc.
Once you're all signed out of your iTunes/iCloud account, you can create a new account. Go to Settings > iCloud and tap Create a new Apple ID. You'll be asked to enter in a birthdate, name, and email address (you'll need to enter in a different email address from your other iTunes/iCloud account).
You'll no longer receive iMessages, FaceTime calls, or iCloud Mail. You lose access to iCloud, the App Store, Apple Pay, Find My, and any apps or services associated with your Apple ID. The email address associated with your Apple ID account will be unavailable for use with a new or existing Apple ID.
However, this will erase everything from your iPhone and return it to factory settings. That may not be a problem if it's an iPhone you've just acquired, but if not, you'll want to make sure you've backed it up to your Mac or PC before proceeding.
You can log in to two Apple IDs for emails (we'll demonstrate that later) but that's pretty much it. Here are some prerequisites that you need to be aware of before you switch iCloud accounts on an iPhone: You cannot sync your purchases or other iCloud data like notes, voice memos, photos, etc. from both accounts.
You can have two iCloud accounts on one iPhone. But there are some limitations. You need to choose a primary account, whether it is your new iCloud account or the old one, for iCloud Drive, iCloud Photos, backup, apps, music purchases, etc.
