The \ character before the * is only necessary to prevent your shell
from expanding the wildcard because you didn't use quotes to escape
your regexp.

In your Squid conf file, you just need:
acl NOCACHEPDF url_regex -i ^http://hostname.*pdf$
acl NOCACHEXLS url_regex -i ^http://hostname.*xls$

But if I were you, I'd use:
acl NOCACHEXLS url_regex -i ^http://hostname/.*\.xls$
acl NOCACHEPDF url_regex -i ^http://hostname/.*\.pdf$
which is more precise and more correct IMHO.

Or shorter:
acl NOCACHE url_regex -i ^http://hostname/.*\.(pdf|xls)$
