It's not that bad from what I can see.
I think the recording is Bach/Gounod "Ave Maria".
Looks like the "London Promenade Orchestra, Eric Hammerstein" recording is wrong since that one also has another AcoustID.
Attribution to Schubert is probably just confusing the two common "Ave Maria" works.
Lots of the recordings are on Delta Music labels (Delta, Laserlight Digital, Reader's Digest -- see https://en.wikipedia.org/wiki/Delta_Entertainment_Corporation )
So that leaves the Salzburg Consort (likely Alfred Scholz fake artist) and the additional "unknown" which seems to point to "the ultimate classical collection: 101 essential classics".
Probably the best option is to try to verify the AcoustIDs on that release and the brasilian release, https://musicbrainz.org/release/5b6f5d62-a4bd-4a39-a690-3dfda358d7a7
