Best Practice on G+???: International/multilingual sites

Hi Erveryone,
I appologize if this question has already been asked and answered.

As the title say, i am quite interested in knowing the best practices for multilingual sites on G+

Atm. out website has the following structure:

BRANDNAME.com (English)
BRANDNAME.com/de (German)
../se (Sweden) etc.

For each country we have created a separate G+ page (BRANDNAME Deutschland, BRANDNAME Sweden etc.)

#1. Is this the right approach or would it be better to only create ONE G+-Site? If yes, is there then any way to localize the content of the G+-Site?

#2. If no in #1, and we should stay with the approach with separate G+-Sites - How should we then link the G+Sites and website together?

Like this: ? (Url --> G+-Site)
- BRANDNAME.com --> BRANDNAME
- BRANDNAME.com/de --> BRANDNAME Deutschland
- BRANDNAME.com/se -->BRANDNAME Sweden
etc.
Will this lead to complications country specific sites beeing connected to 2 sites?

3#. What would be the best approach concerning the Author - same G+ profil as author for all websites?

Any help and experience is thankfully appreciated since i am quite new to G+.
