If the links hit different pages on your site, then there will be considerable benefit to those individual pages. If the links all hit the same page, then the benefit of multiple links is not as much.

Hello Domain Authority in Moz is Moz's own score of your site/site health and it's backlink profile. Google has its own ways of grading your site. Google is not affected by Moz's domain authority score but it my experience, a higher domain authority has correlated with higher rankings and more traffic.
