Answer 1

To run your app must be installed and located (if not, will open default language)

Use this command to run your app with some language

xcrun simctl launch <deviceid> <appid> -AppleLanguages "(pt-BR)"

Sample:

xcodebuild -sdk iphonesimulator8.4 -arch i386 install DSTROOT=SomeFolder
xcrun instruments -w "iPhone 6 (8.4 Simulator)"
xcrun simctl install booted SomeFolder/Applications/YourApp.app
xcrun simctl launch booted com.yourdomain.yourapp -AppleLanguages "(pt-BR)"

Have a look at:

Perhaps it could also be a solution creating different targets. Each target has configured another language

Answer 3

The only way to launch iOS Simulator with specific language is to change contents of its .GlobalPreferences.plist file. Using xcrun tool will not work because it passess arguments to launched app and not changing language of simulator itself. Manipulation on .GlobalPreferences.plist is quite difficult because it is a binary plist file, so you cannot modify it as 'normal' xml. The easiest way to change its contents is to write simple Xcode Command Line Tool application, Foundation SDK has all tools needed to modify binary plists.
