Answer 1

Have you the same number of rows on thre tables ?
If yes, try :
SQL> select a.sno as sno1, b.sno as sno2, c.sno as sno3
  2  from (select sno, row_number () over (order by sno) rk from tableA) a,
  3       (select sno, row_number () over (order by sno) rk from tableB) b,
  4       (select sno, row_number () over (order by sno) rk from tableC) c
  5  where a.rk=b.rk
  6* and   b.rk=c.rk
SQL> /
      SNO1       SNO2       SNO3
       101        101        101
       102        102
       103
