How can I know what's the owner of a file in finder > get info?
The top name in the Get Info's Sharing & Permissions section will be the file owner. A file owned by root will show system as the user.
The following AppleScript one-liner will display the user name associated with the selected file icon — just to confirm the first sentence.
tell application "Finder" to display dialog (owner of item (selection as alias)) as text
sorry mate, isn't the owner the bottommost listed user? that's what I found yesterday, sorry I didn't update the post
Not sure if the order is deterministic, and the names used for the users do differ. User root is shown as system in Finder, for instance.
Launch Terminal.app and use ls -ale or ls -aled to have a look for yourself.
$ ls -aled /Applications/Safari.app
drwxr-xr-x+ 3 root wheel 102 Mar 30 08:49 /Applications/Safari.app
0: group:everyone deny delete
$
Above app bundle (which is a directory, hence the use of -d in -aled) is owned by root, and the group is wheel.
Finder doesn't appear to display the underlying ownership and group settings directly. Which may well be deliberate.
The Get Info Sharing & Permissions entries are listed in the following order from the top just as they are indicated in normal UNIX permissions read from left to right. This is explained in detail in the chmod(1) man page.
To know the owner: select the file or folder, press Command+i (or File > get info), then you'll see the permissions listed in the order you listed:
user
group
other
so, if there're permissions for several users, you'll see them listed first, THE BOTTOM-MOST USER IS THE OWNER. So, in the picture above: test is the owner of the file.
I do not have a multi-user machine, nor do I share files with others on a server. Thus, the default ownership on my OS X is me (or system), and the owner, group, and other hierarchy that I specified is all that ever has appeared on my Mac.

The following is from Safari on one of the local systems. In this case, the owner is the second entry shown, and the first entry is for an access control list entry.
$ ls -aled /Applications/Safari.app
drwxr-xr-x+ 3 root wheel 102 Mar 30 08:49 /Applications/Safari.app
0: group:everyone deny delete
$
How can I know the owner of a file in OS X?
