Majority of pages not indexing

Sorry for so many questions.

I have tried to fix an indexing issue, it was at 15 pages indexed now at 22. Any idea how im meant to fix these further?

for instance with the crawled but not indexed pages, as ive checked every page and they are all ticked to be indexed on. mODX - what else would need to be done?

Pages with redirect is just for info so no need to worry about that. ‘Not found’ could mean that the url / uri has changed. Currently not indexed could indicate that the quality of the content of the page isn’t deemed to be good enough to be indexed.
