You can use a hash and populate it based on a list with map:
my %names = map { $_ => '' } qw(foo bar baz);
print "$names{$_}\n" for keys %names;
# access individually
print "$names{foo}\n";
You can also use an array, but it'll only work if your variables are truly in a numbered order. Note that an array starts at zero and not one though. If your vars aren't literally ordered, use a hash instead.
my @names = ('') x 6;
# the following is wrong, pointed out in the reply by mr_ron
# my @names = '' x 6;
print "$_\n" for @names;
# access individually
print "$names[2]\n"; # prints 3rd element
