for r1 in c1 loop
v_total_rec := ? ( i would like to know total rows in the cursor , say for example if cursor has 10 rows, i want10 into this variable )
v_count := v_count +1;

Even though cursor loops are generally a Bad Idea ^tm^ as Dan says, here's an example of how you can get the information you wanted within the query itself...
SQL> ed
Wrote file afiedt.buf
  1  declare
  2    cursor c1 is
  3      select emp.*
  4            ,count(*) over (order by empno) as cnt
  5            ,count(*) over () as total_cnt
  6      from emp
  7      order by empno;
  8  begin
  9    for r1 in c1 loop
10      dbms_output.put_line(r1.ename||' - row: '||r1.cnt||' of '||r1.total_cnt);
11    end loop;
12* end;
