Hi,
PATCH_SUPEE-9767_CE_1.9.3.0_v2-2017-07-11-11-04-56.sh will have been the right patch to apply. It doesn't upgrade you to 1.9.3.2, just applies the required security patch.
Unfortunately, there's no quick solution here. There's pretty much only one reason that patches don't apply and that's that the code that they're looking for to replace/update isn't where the patch is expecting. You will need to apply the first patch again but investigate each time where it fails to apply, look at the file and lines it's trying to find and replace and identify why it's not working. Manual resolution is possible though a bit time-consuming.
The patches are written in such a way that assumes that you have correctly applied all previously released patches so that could be one reason why they're not applying successfully.
