Sure. If someone links to them, or they're discovered some other way.
If you don't want them indexed, you need to slap a robots meta tag of NOINDEX on them.
And then you need to remove the disallow in robots.txt, because if Google isn't supposed to crawl them, they won't see the NOINDEX.
robots disallow is for crawling.
robots meta tag is for indexing.
Crawling and indexing are not the same thing.
