BenRG has a point about Applejack clearly stating that "the pony nation" extends beyond Equestria's borders, but here's something from The Super Speedy Cider Squeezy 6000:

Flam : We don't care if the whole kingdom of Canterlot helps.

Therefore, Canterlot has been called a kingdom on the show. Furthermore (using this method, I found out that), Spike states in Equestria Games that Cloudsdale is a part of Equestria (along with Rarity stating in Sonic Rainboom that Cloudsdale is a city). Our Town is... well, a town, meaning it has no governmental powers, while cities like Cloudsdale do.

But as for Griffonstone being part of Equestria, here's something from The Cutie Map - Part 1:

Spike : This is incredible! It's got all of Equestria!

Therefore, whatever's on the map is a part of Equestria. And then there's the Friendship Rainbow Kingdom.
