If all the lines are in an array, you could use grep to find each line. Arrange the tests in the order that you want the output. 
C:\Users\Bill\forums\monks>type eshan_k.pl
use strict;
use warnings;
my @text = do{undef $/; <DATA>};

my $line;

($line) = grep {/LumaIntraMode/} @text;
if ($line =~ /\s*APP>\s*LumaIntraMode\s:(\w+),\suse_intrabc:(\d)/i) {
   print "Luma_mode = $1\n";
}

($line) = grep {/\sAPP\>\sIntraAngleDelta\s\:\s/} @text;
if ($line =~ /\s*APP>\sIntraAngleDelta\s:\s(\d+)\s(\d+)/i) {
   print "Luma Angle : $1\n"
}

($line) = grep {/ChromaIntraMode/} @text;
if ($line =~ /\s*APP>\s*ChromaIntraMode\s\:(\w+)/i) {
   print "Chroma mode: $1\n";
}

($line) = grep {/ALPHA_U\:/} @text;
if ($line =~ /\s*ALPHA_U: (\d+), ALPHA_V: (\d+), CFL_ALPHA_SIGN: (\d+)
+/i) {
    print "CFL : $3\n";
}

($line) = grep {/\sAPP\>\sIntraAngleDelta\s\:\s/} @text;
   if ($line =~ /\s*APP>\sIntraAngleDelta\s:\s(\d+)\s(\d+)/i) {
   print "Chroma Angle : $2\n"
}
