Is it possible that I only have one (new) email address for my existing Google accounts with different email addresses?

Okay, this is with me:

I have several YouTube channels, each with a different topic. At that time I didn't know that you can have an account / channel and then add other accounts without having to make a new email address. I did a lot on my cell phone and you never read anything about this function. That's why I have a separate email address for each of these Google accounts. Well, now I have 5 email addresses… Don't worry, not all of these channels are still actively used xD. But it's really a bit stupid. You get everything communicated to different addresses and if you log in somewhere else, you don't know which email address to use.

Most of these email addresses have something to do with my own first and last name. I think that's a bit stupid because then I can't just send my email address to anyone on YouTube without the person knowing my name. Via these email addresses, which contain my name, things like memberships etc. Also run. So also private things and I never know which address to give.

Therefore I would like to do the following, but don't know if it is possible:

I would like to make a completely new email address that does not contain my first or last name. Or would it also be possible to simply rename an email address? I can then send this to anyone without them knowing any private data. I would like to manage all my Google accounts via this email address. But I don't know if this is possible because the Google accounts all have a different email address.

I would like to keep one of the existing email addresses that contain my private name in order to use it privately and delete the others. But is it that easy?

Can I forward everything to the email addresses that I still keep or create? If I now delete an email address, what happens to other accounts to which it is linked? So if I log into Minecraft, for example, with an email address that I then delete, will my Minecraft account also be deleted? Or can I make it so that my email address is automatically changed for all accounts, for example games, to the address I keep? Or can you only change it manually in each game (we're not just talking about games, in general when I leave my address for a club, for example)? Because changing it manually would be stupid, I don't know where I have registered. Will emails that I have written with the deleted accounts also be deleted or can I somehow forward this to the others? Or should I do it so that I still keep the other email addresses, but simply don't use them? If it doesn't work, link and forward to another email address.

I know, I've been writing for a long time now and I hope that someone reads through it and understands it;)

Separate YouTube channels can't be merged or linked. Automatic data transfer from one channel to another is also not possible.

https://myaccount.google.com/permissions under this link you can see all websites that are connected to the respective Google account. Unfortunately, you will have to manually add these accounts to your new account.
Your Minecraft account will not be deleted when you delete it from the Google account, but you should make it clear in advance that you know the access data for this account or that you provide a recovery address.

So it is not possible to change the email address of a channel either?

Unfortunately no, this only works with a "brand account" by adding an administrator & then downgrading yours.

Sry, I seem to have written a complete rubbish. Here is a link to instructions.
