You can return multiple results as:

Array
return ($all->[0]->{$field_name}, $first_cell);
Arrayref
return [$all->[0]->{$field_name}, $first_cell];
Hashref
return {field_name => $all->[0]->{$field_name}, first_cell => $first_cell};

Of these, I'd pick one of the references as these package the data and you're only passing around a single scalar value. Further, I'd choose the hashref over the arrayref because you're not restricted to the order of the results and dealing with the returned values is easier and more readable. Consider: 

my $h = hlookup(...);

# First cell value with arrayref
my $first_cell = $h[1];

# First cell value with hashref
my $first_cell = $h{first_cell};
