Can I have 2 iPhones on the same Apple ID account

Can I have these 2 phones on my Apple account

Yes, but there are advantages and disadvantages here.

The advantage.......you won't have to purchase apps for the new phone because the apps are tied to your Apple ID account.

A possible disadvantage......your call history will appear on both phones.

Reply is that email address is being used already and I am unable to do so

I have had two on the same Apple ID for just over 2 years now, they both used to ring when one line was called, my watch used to ring for both numbers as well, I could answer at work on my watch if my other line had received a call. Some months back after an update that stopped happening.

That just means that the developer has removed the app from the store. They will remain on a phone that had previously downloaded it, but you will no longer be able to download it onto another phone.

You can't set up a new Apple ID using the same email address as one that had been used already, but you certainly can sign into another phone using that Apple ID email and password.

How do we get about doing the backup thingy? Just back the stuff on our old iPhones to the iCloud and then when setting up the new phone how do we get the backup there? Like at what point do we get asked if we want our backups on the new device? And what if it’s a hand-me-downer…already been used by someone? Will that affect whether we’re able to access the backup or not?

After a phone is factory reset, it will startup up with the options on how you want to set it up.

The apps were available some time ago when you first downloaded them on the "old" phone. But, you now have a "new" phone and in the meantime the developer changed or discontinued the apps.

Yes backup to iCloud to do so go into settings, tap on your name then iCloud. Factory reset the phone, use the same Apple ID for the new (or hand me down) phone and follow the prompts, it will ask you during setup if you want to use a back up from iCloud, if you haven’t been backing up, then you’ll probably just have the one to choose from. Make sure that the iCloud settings include apps and passwords etc… everything should be carried over (everything except passwords saved in browsers).

But when I am trying to download the apps which are in my other phone it is saying “item is no longer available.”

Have you tried installing them via a backup of your old phone? When you set up the new phone it will give the option.
