This ROM do not offer Slovenian language. So i need help what to do to have Slovenian android version. It is not metter even if it is 2.3 version. Only that it has official android with Slovenian language.

Any idea how to use my device with Slovenian language?
I would recommend installing a custom ROM with support for the language you need. I think CyanogenMod might be a good try since it's usually very stable and close to "stock" ROMs of Android. You can find the stable CyanogenMod version for HTC Desire S here.

Rooting and flashing ROMs on your device might require some work on your device if it's not rooted, or if it's rooted it might be quite simple. Since you don't offer any information on whether you are rooted or not, here's some resources for you to look up:

All of this is of course assuming that your current Android version does not support changing the language. You might want to look in your menus just to make sure. If it's not there, you need to get another ROM.

If you have any questions, please comment on this answer and I'll try to expand on it accordingly.
