The answer to the new question is: There is no plural of the word “a” because once a word is no longer singular (i.e., as when “a dog” becomes “dogs”), there is no longer any need for an indefinite article.
“A dog” when plural becomes either “dogs,” with no article, or “some dogs.” The word “some” is a quantifying adjective, not an article.
