You have to explain much better what you are actualyl trying to animate in what manner, which file formats you intend to use and so on. Just throwing out generic "Can I...?" questions is of no use to anyone.
I have made some cartoons that are up on the web.
Check out the one "slake". That cartooning is the best I could get in Adobe Animate. After Effects had a new (to me) animation program that would allow me to doctor up the simple drawings and make the whole scene better.
The only thing I see on your web page is some links to some MP4 files.
I would suggest you embed them in your site to make it look better. Use YouTube or Vimeo. With most browsers the movie files will just download.
If you are producing MP4 animations then that's where After Effects shines but there is a learning curve and the animation techniques are completely different than they are in in Animate. You cannot take an AE file and use in in Animate as anything but a movie. To get started with AE look here: Basic AE
