loop difficulty

ctsgnb! you so kind and helped me alot to understand more unix.
I would like to ask if we have e.g 7 or less names and we want to select three names of them in one go and test them that are included in our pre-created names(for example they are file names),what is the best solution?I have used IF statement but it seems very long statement as I had to test it for each name (for example each variable should not be blank or other things).my question is do we need to check each variable or there is simple way exist?
for example:
echo "benz bmw gms nissan polo"
echo "select four names out these names:\c"
read name1 name2 name3
while [[ $name1 = "" ]]
do
echo "no entry"
read name1 name2 name3

while [[ $name2 = "" ]]
do
echo "no entry"

echo "Please enter your choices: \c"

read name1 name2 name3

while [[ $name3 = "" ]]
do
echo "no entry"
echo "please enter your choices:\c"
read name1 name2 name3

if [[ -f $name1 ]]
then
echo "$name1"
else
echo "$name1 does not exist"
fi

if [[ -f $name2 ]]
then
echo "$name2"
else
echo "$name2 does not exist"
fi

if [[ -f $name3 ]]
then
echo "$name3"
else
echo "$name3 does not exist"
fi
done

It would be so appreciated if you can see where I am in wrong place?
Regards

gss_compare_name

gss_compare_name(3)					     Library Functions Manual					       gss_compare_name(3)

NAME

       gss_compare_name() - allow an application to compare two internal names to determine whether they are equivalent

SYNOPSIS


DESCRIPTION

       The routine lets an application compare two internal names to determine whether they are the same.  This routine does not resolve the names
       to see if they refer to the same object.  It simply compares the input names for equivalence.  If  either  name	presented  to  denotes	an
       anonymous principal, the routines should indicate that the two names do not refer to the same identity.

   Input Parameters
       name1		     Specifies the first internal name.

       name2		     Specifies the second internal name.

   Output Parameters
       name_equal	     Returns one of the following values:

				The names are the same.

				The names are not the same.

       minor_status	     Returns a status code from the security mechanism.

STATUS CODES

       The following status codes can be returned:

       The routine was completed successfully.

       The name passed by the	name1 or name2 parameter is unsupported.

       An invalid name was passed by the
				name1 or name2 parameter.

       The routine failed.  Check the
				minor_status parameter for details.
