After re-read your question I think I got a solution with UTL_FILE, I think I didn't understood the question at the beginning.
Here is a small example, but you need to change it to your needs:
SQL> declare
  2      numbers   varchar2 (32767);
  3      names     varchar2 (32767);
  4      deptos    varchar2 (32767);
  5      f1        utl_file.file_type;
  6 
  7      cursor employees (v_numbers in varchar2) is
  8          select empno, ename, deptno
  9            from emp
10      /* the following subquery do the IN VARLIST
11      you need to add for each one you want*/
12           where empno in (
13                     select     substr (txt
14                                       , instr (txt, ',', 1, level) + 1
15                                       ,   instr (txt, ',', 1, level + 1)
16                                         - instr (txt, ',', 1, level)
17                                         - 1) as token
18                           from (select ',' || v_numbers || ',' txt
19                                   from dual)
20                     connect by level <=
21                                      length (v_numbers)
22                                    - length (replace (v_numbers, ',', '') )
23                                    + 1);
24  begin
25      f1 := utl_file.fopen ('TEMP_DIR', 'TEST_DATA.TXT', 'R');
26      utl_file.get_line (f1, numbers);
27      utl_file.get_line (f1, names);
28      utl_file.get_line (f1, deptos);
29      utl_file.fclose (f1);
30  
31   dbms_output.put_line ('============Values from the file===========');
32      dbms_output.put_line (numbers);
33      dbms_output.put_line (names);
34      dbms_output.put_line (deptos);
35 
36      dbms_output.put_line ('===== Doing the cursor with the IN values from the file ===');
37   for v_emp in employees (substr (numbers, 4) ) loop
38          dbms_output.put_line (   v_emp.empno
39                                || '-'
40                                || v_emp.ename
41                                || '-'
42                                || v_emp.deptno);
43      end loop;
44  end;
45  /
============Values from the file===========
No:7369,7499,7521
name:jones,martin,blake
depno:20,30,10
===== Doing the cursor with the IN values from the file ===
7369-SMITH-20
7521-WARD-30
7499-ALLEN-30
PL/SQL procedure successfully completed.I think the complicated part for that is the VAR INLIST, you can user Tom's function examples if you don't want to use the long query option, like in your case you will be using several of them.

I'm doing several assumptions here, like 3 lines in the file, the first "part" of the first line is "No:",etc.
