Answer 1

The smaller front number are the current installations known to Google. The larger second number is the total of installations through the Play Store. I'm not sure whether these are for unique users or just the total of downloads.

Answer 2

When you hover mouse on "?" in title header it shows you Current Installed/Total Installed .

Current Installed : Number of unique active devices where the app is currently installed.

Total Installed : Total number of unique users who have ever installed this app on one or more of their devices.
