Answer 1

Try this awk

% awk '/File:/{ n=split($2,arr,"/"); print "filename:",arr[n] }
       /Access:.*Uid/{ gsub("\(|/.*","",$2); sub("\)","",$6);
          print "owner:",$6"\npermissions:",$2 }
       /Size:/{ print "size(Mb):",$2*0.000488281 } 
       /Birth/{print "------"}' file | column -t
