yes, you're only missing commas:

@array1 = qw( a b );
@array2 = qw( c d );
@array3 = qw( e f );

foreach (@array1, @array2, @array3) {
   print;
}

# output
# ------
# abcdef

If you wanted to go through them in parallel:

@array1 = qw( a b );
@array2 = qw( c d );
@array3 = qw( e f );

# Assumes all array are the same length.

foreach (0..$#array1) {
   print($array1[$_], $array2[$_], $array3[$_], "\n");
}

# output
# ------
# ace
# bdf
