Hello Aridium, the frame size is 192x192 (RPG Maker default I think)
You can see how much frames on each animation above, the speed that I use myself is 6 to 8 frames per second, depending on the animation, but that you can decide however you want.
is there a way to make this as apng instead of png? I know this is weird but to be bluntly honest I don't know how to use the current png version :(
I will take a look into it, I will write you again. :)
