Thank you for writing.
That appears to be Apple Antracnose Canker that is fairly far advanced. https://s3.wp.wsu.edu/uploads/sites/2109/2014/12/AppleAntracnose20121.pdf
If you wish to try to save the trees, you should consult with a certified arborist to confirm the diagnosis. https://extension.umn.edu/planting-and-growing-guides/how-hire-tree-care-professional
