Since I'm not Irish, any answer I gave you would by definition no longer be true, and even if I were, if you're not Irish and you used it, then again there's a problem here.If you want a stereotypical Irish saying, there's "Erin go braugh", which means "Ireland Forever".
Irish has no single words for 'yes' or 'no' as does English.
"dann" and "dainne" are not Irish words.
