English Comprehension in Caucas Countries

I'm doing some thesis market research on the comprehension of the words "stretch" and "Limited Edition" on various packaged goods in the Caucas countries: Armenia, Georgia, Azerbaidjan, Kazakhstan, Kyrgystan, Mongolia, Uzbekistan, Turkmenistan, and Tajikistan. Could these phrases be understood by native speakers of the above-mentioned countries if they were printed in english? or Russian? Thanks for any help or suggestions!
