As far as a newbie can go, LGTM.

Is there any reason for why the bottom left sprites have these different borders from the other ones? Its like the rest of the atlas is "bleeding" out in each square. Sorry if this is obvious.

yep it's called texture bleeding. The colors are blended across the edge of the sprite with neighbouring pixels from the atlas texture.
