1. Unfortunately its of all users in that federation. They are all Skype users. In my admin center we have activated the "Allow users in my organization to communicate with Skype users." option.
2. Yes similar to the screenshot above the external users can even contact me, but I cannot answer.
With other external users / service providers we don't have any issues. I will DM my contacts with you for federation check.

I'm currently looking at a similar issue.
Tenant 1 is Teams Only (upgrade from hybrid Skype for Business) - unable to communicate with multiple external Skype for Business estates.
Tenant 2 is Teams Only - able to communicate with the above external Skype for Business estates.
I'm performing the Tenant 1 and Tenant 2 tests from the same machine/network. Microsoft say the issue is with the external Skype estate(s). Sounds like a config issue with Tenant 1?
