Can I transfer google play data to another gmail account address?
No, you can't. However for games, based on this answer:


  the answer is it depends "on how the game data is saved by the developer"  For most games, no, you can't move their progress from one account to another.  But, some games do have that ability.
  
  You'll have to check with the developer of each game directly to see if they have coded that ability for their game.  Google doesn't have an overarching way to move data.
