Regular files show their sizes by the icon size.
The biggest file in a directory gets the biggest size.
The smallest files all get the same size icon.
Empty files (zero bytes) appear torn off at the bottom
(see the last icon here).
Directories also use the size of the icon to show you the relative size of the file.
A torn-off folder represents a directory with no files
(except for the . and .. files).
A hollow outline around a directory indicates that Interrogator has not fully tallied up the contents. The inner icon shows the total size of what has been tallied up so far. The outer icon size shows the maximum possible that might be inside, if, by total coincidence, all of the untallied bytes on the volume turn out to be inside this particular directory. (This is unlikely.)
A folder icon with bars, like a jail, means that somehow you don't have permission to tally through the directory. Therefore, it is not fully tallied, and it will never become fully tallied (unless you unexpectedly gain access).
A disk icon means that this directory is a mount point for another volume.
Mac applications are diamond icons.
Actually they are directories, but with magical attributes.
Similarly, Mac Packages are directories.
In both cases, the finder tries to treat them as though they were individual files.
Symbolic links show the kind of file they point to.
The red box with the question mark is a file of indeterminate type,
because this symlink points to a file that does not exist.
Network socket devices look like an 100Base-T Ethernet receptical.
Pipes look like pipes, of course.
A character device looks like a rounded trapezoid;
it is meant to resemble an old-style RS-232 connector.
Block devices similarly look like SCSI or Parallel Port connectors.
