Answer 1

Here we go, in a Single Statement Block
SQL> ed
Wrote file afiedt.buf
  1  DECLARE
  2    v_cnt NUMBER := 0;
  3    v_tot NUMBER := 0;
  4    CURSOR cur_tables IS
  5      SELECT table_name FROM user_tables;
  6  BEGIN
  7    DBMS_OUTPUT.ENABLE(1000000);
  8    FOR t IN cur_tables
  9    LOOP
10      EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM '||t.table_name INTO v_cnt;
11      v_tot := v_tot + v_cnt;
12    END LOOP;
13    DBMS_OUTPUT.PUT_LINE('Total Table Rows: '||v_tot);
14* END;
SQL> /
Total Table Rows: 5850553
PL/SQL procedure successfully completed.
SQL>What use it is is anybody's guess.
Note: This only works on the users own tables, not all the system tables or tables from other schemas in the database.
