my installation of ox-freemind.el:

- put ox-freemind.el in list/org - directory
- (require 'cl) in init.el
- custom settings in initl.el: 
 '(org-export-backends (quote (ascii beamer html icalendar latex freemind)))
 '(org-freemind-pretty-output t)
 '(org-freemind-style-map-function (quote org-freemind-style-map--automatic))

run C-c C-e f f in org-buffer
open in freemind or freeplane current version (no difference, all branches always placed to the right of main subject).

It is getting placed rightly.

Here is the screenshot of what I get (with no additional customizations
at my end).  I use freeplane, btw.

As for styles, you need to customize your styles in Freemind exporter
and move over the XML to ox-freemind.el.  If you have a specific
question wrt style, I can help.  But I need to be convinced that you are
using the right exporter i.e., no installation issues etc etc etc.
