Multiple Cronjob from Single Execution

I am reading through out this forum and dreamhost wiki pages to know how to set up a cronjob. I have a movie site running on wordpress which required three files to execute daily. I understand that it’s easy to setup a cron jon through DH control panel. But I have two doubts.
[]How can I setup multiple cron job in a single file?
]My loaded php configuration file (php.ini) from different location(cgi-bin). Does it affect the setup?
I would like to setup the following lines in my control panel according to this thread. Could you tell me am I wrong?

/usr/local/bin/php /home/USER/DOMAIN/script1.php
/usr/local/bin/php /home/USER/DOMAIN/script2.php
/usr/local/bin/php /home/USER/DOMAIN/script3.php

Is it possible to run multiple files in single execution?

ooooooops it does not working. getting errors like following
Warning: copy(…/dwimages/0479997.jpg): failed to open stream: No such file or directory in /home/user/ on line 189
Warning: include(): URL file-access is disabled in the server configuration in /home/user/ on line 418

I think this error for "allow_url_include = off’ . That’s why I installed a custom configuration and used custom php.ini How can I solve this?
