Answer 2

1. Create a list of all required user groups and roles.
2. Translate into English (if they are in Russian, and vice versa), creating copies in all available (for nicknames) languages.
3. Combine rows into clusters.
4. Write bounding regular expressions for each cluster.

Answer 3

It is entirely up to you which nicknames to reserve.
You can at least use a regular expression to pick up all the admins, moderators and support agents.

Answer 5

If we talk about logins, then

Or are logins in 2020 already bad manners?

That's right
. And it's not that bad manners, but a hell of a headache.
And, most importantly, it is completely incomprehensible, what the hell is a login if the email is a unique identifier anyway.
But first you need to learn how to distinguish login from username/display name.
Here, apparently, we are talking about the second.
Usually, in normal services, any names are allowed, and administrative accounts are marked with interface tools , and not with a name.
