As your other two parameters are out parameters, at SQL* Plus prompt, declare variables. Something like this.
SQL>create or replace procedure sample_proc(v_in number,
  2  v_out1 out number,
  3  v_out2 out number)
  4  as
  5  begin
  6     v_out1 := v_in * 10;
  7     v_out2 := v_in + 10;
  8  end;
  9  /
Procedure created.
SQL>var a number
SQL>var b number
SQL>exec sample_proc(10, :a, :b)
PL/SQL procedure successfully completed.
SQL>print a
        A
      100
SQL>print b
        B
       20
SQL>Cheers
