I believe the structure <DATA> only returns ONE line at a time...

You need to put it in a loop...

$state = 0;
$line = <DATA>;
$state = 1 if $line =~ /#ddffff/i;
while (<DATA>){
$keep_line = $_ if ($state && $_ =~ /NC_/);
# Now do something with $keep_line to persist it...
$state = 1 if $_ =~ /#ddffff/i;
$state = 0 if $_ =~ /^\s+&/;
}

Assuming blank lines between paragraphs, set a $state variable to 1 (some TRUE) value if you encounter a /#bbffff/ line... Now with the state set to TRUE, look for your NC_ pattern and save the line. The next blank, set state back to zero so that the next paragraph will NOT be searched unless you find #ddffff etc. There's probably a more elegant way to do it, but this should get you started...
