Of course it's possible - it wouldn't be Perl otherwise..

You can even do funky stuff like: my @lines = map {<$_>} map {$fh[$_]} <>; though it's usually likely to shoot yourself in the foot in the process...

Note that on some OSs there is a noticeable limit on the maximum number of files open - but no, 3 won't trigger it.. more like 255..
it doesn't look like you want to write to some of those filehandles, but in case you do decide to, Perl will complain.. from 
perldoc -f print

Note that if you're storing FILEHANDLES in an array or other
expression, you will have to use a block returning its value
instead:

    print { $files[$i] } "stuff\n";
    print { $OK ? STDOUT : STDERR } "stuff\n";
