Return to Neverland
Jungle Book 2
You start to get tricky here. I'd avoid counting either of those movies for one simple reason, they aren't Walt Disney Animation.
They were created by a division within the Walt Disney Company known as Disney Toon. They're responsible for movies like Cinderella 2, Planes, and Mulan 2.
They actually made some pretty good movies, but they also made crap that disgraced their namesakes.
The division has (or had) the right to take the look and feel of existing movies and make spinoffs.
Upon the Pixar buyout, Disney Toon stopped its strategy partially because they had run out of movies to sequel but mostly because they'd damaged the brand.
Planes and The Tinkerbell Franchises were their work. Successful too. Now finally they seem to be meeting their fate.
Layoffs were announced recently.
Also off the top of my head along with the two you mentioned was Piglet's Big Movie, Tiger's Movie, and the Heffalump Movie. They'd fit under your criteria as well I believe.
I just don't view any of those movies as canon because they weren't made by the studio that created them.
