Since you mention you're using database version XE, I'll assume you're database version is at least 10.2
SQL> select * from v$version;
BANNER
Oracle Database 10g Express Edition Release 10.2.0.1.0 - Productand so you have the power of:
- external tables
http://www.oracle-base.com/articles/9i/ExternalTables9i.php
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:6611962171229
- regular expressions

and you don't want to be using SQL*Loader anymore, never ever.
I simply put your string 'Shahzaib ismail, Imran aziz, Shahmir mehmood, Shahzad khan' in a file called test.csv and told Oracle that file is in my Oracle directory DATA_DIR (that actually points to: c:\data on my 'filesystem' ) and then:
SQL> create table t(name varchar2(155));
Table created.
SQL> -- instead of SQL*Loader use an External Table:
SQL> create table ext_t
  2    ( textstring varchar2(4000)
  3    )
  4    organization external ( type oracle_loader
  5                            default directory DATA_DIR
  6                            access parameters (fields terminated by '' )
  7                            location ('test.csv')
  8                          );
Table created.
SQL> -- Now you can query your file as if it were a table!                       
SQL> select * from ext_t;    
TEXTSTRING
Shahzaib ismail, Imran aziz, Shahmir mehmood, Shahzad khan
1 row selected.
SQL> -- and use the powers of SQL to do whatever you want (instead of cludging with those dreaded ctl files):
SQL> select regexp_substr (textstring, '[^,]+', 1, rownum) names
  2  from   ext_t
  3  connect by level <= length(regexp_replace(textstring, '[^,]+'))+1;
NAMES
Shahzaib ismail
Imran aziz
Shahmir mehmood
Shahzad khan
4 rows selected.
SQL> -- Voilà, the data is loaded into the table in one single SQL statement:
SQL> insert into t
  2  select trim(names)
  3  from ( select regexp_substr (textstring, '[^,]+', 1, rownum) names
  4         from   ext_t
  5         connect by level <= length(regexp_replace(textstring, '[^,]+'))+1
  6       );
4 rows created.
SQL> --
SQL> select * from t;
NAME
Shahzaib ismail
Imran aziz
Shahmir mehmood
Shahzad khan
4 rows selected.Don't use SQL*Loader, use an External Table.
