Not very clear to me, but 1st pic (1354) looks repairable. The 2nd pic (1355) is doable assuming the outside fileting (fairing) is removed, as one usually needs access to both sides for a proper repair job.
Using the search tool you will find many threads here dealing with the subject.
As far as the parts list for replacing the canopy, this will be found, as usual, on Van's website. Buying a canopy is one thing (shipping costs are crazy nowadays, you've been warned), but adapting the "glass" to the frame is another. Looks like we're talking about a slider here, so first the big cut would have to be done... talking about a lot of work here... so assuming you can't/don't wanna work on your baby, you'd rather first hunt for somebody willing/able to do the whole works.
Good luck
