What %~2 means ?

Answer 1

From ftype /?:

Within an open command string %0 or %1 are substituted with the file name being launched through the assocation. %* gets all the parameters and %2 gets the 1st parameter, %3 the second, etc. %~n gets all the remaining parameters starting with the nth parameter, where n may be between 2 and 9, inclusive.
