Can't Restart Apache

We are unable to restart apache on our server, as a result no sites are accessible in the browser. Our host states we need to clear out the following files:

[root@server1 logs]# ls -lAh|grep -v ' 0 '
total 1.9G
-rw-r--r-- 1 root root 92M Jul 17 07:55 access_log
-rw-r----- 1 root root 463K Dec 9 2007 audit_log
-rw-r--r-- 1 root root 1.2G Jul 17 07:57 error_log
-rw-r--r-- 1 root root 6 Jul 17 07:42 httpd.pid
-rw-r--r-- 1 root root 92K Feb 18 2008 ssl_engine_log
-rw-r--r-- 1 root root 535M Jul 17 07:46 suexec_log
-rw-r--r-- 1 root root 10 Jul 17 03:21 suexec_log.offset
-rw------- 1 root nobody 5.6M Dec 10 2007 suphp_log

Is it ok to simply delete these files? If so, will they recreate
themselves?
