Cani have an Apple email address to give out so my friends can email me?

The 3 addresses are all from the Apple server. They are the same account.

See if anything here helps.

iCloud - Create or change email aliases

If you log into your Apple ID, do you see an @iCloud,com, @me.com or @Mac.com address under the Reachable At section? If so, those are email addresses.

You are welcome.
