The formatting of the output is awful, you can use [code][/code] tags to prevent that and make things easier for us.
There is no unused partition, c is a special partition representing the entire disk.
If you created your OpenBSD A6 (MBR) partition without saving any space for your FAT32 partition, you will probably be unable to salvage your current disk configuration.
Please post the full output of fdisk/disklabel again, but use the formatting tags I mentioned above.
