Separate images from one png all same size

Quote:it's preferable if all images have same dimensions. How do i pad the images out of empty space so they all have same dimensions?

All sorts of ways, but once you have your split up images, select the largest, and use Image -> Canvas size to adjust to a 'convenient size'
Repeat using the same size for the othe images. example: https://i.imgur.com/oyZSIRy.jpg
