Answer 1

The QUERY function provides this ability. The "IS NOT NULL" argument works with numbers, and "!=" is for Strings (anything that's not just numbers).

=QUERY({IMPORTRANGE("YourKey","SheetName!A:B");
IMPORTRANGE("YourKey,"SheetName!A:B");},
"SELECT Col1, Col2 WHERE Col2 IS NOT NULL")

Or

=QUERY({IMPORTRANGE("YourKey","SheetName!A:B");
IMPORTRANGE("YourKey,"SheetName!A:B");},
"SELECT Col1, Col2 WHERE Col2 != ''")
