Эти последние пять красивых столов

Can anyone here give me some insight as to why пять is not in the genitive? I know that numeral 1 applies the nominative singular, 2-4 genitive singular, and 5-9 genitive plural.

By the way, what case does a number ending in 0 like 80 apply?

Or do all numbers above 9 except those ending in a 1, apply the genitive plural?

And so for example with dates, what would the year 2011 Apply, and what case does 2014 govern?

Is 2014 written out something like: двадцать четерынадцати года?
