I’m not sure if these are what you’re looking for but worth a Google I think since they all are told from various points of view but not necessarily in first person.
The girl with the dragon tattoo series
Mrs. Dalloway (The Hours? as well?)
The House of Spirits
The Book Thief
Tuck Everlasting
No Country for Old Men
The Help
The Secret Life of Bees
The Stand
Atonement
Sorry, too late to edit. Thinking about it now, I believe I’m wrong about The Secret Life of Bees.
Willkie Collins’s novel “The Woman in White” (one of the great novels of the 19th century, and terribly underrated), where the events are narrated by different people; the section by Count Fusco at the end shows the events from a very different point of view.
John Barth’s “Letter,” has letters written by different characters that talk about the same events; the structure of the book means things are not in chronological order.
Also The Waves.
A novel I read by Walter F. Murphy, The Vicar of Christ, from 1979.
The main character is first a Marine officer, then Chief Justice of the US Supreme Court, then a monk(following the death of his wife), and then he’s elected Pope.
There are three parts told by a Marine sergeant, a Supreme Court Justice, and a member of the College of Cardinals. BTW, the titular character chooses the name Francis as the name he will reign under. It was his father’s name, but since the cardinal telling that part of the story is Italian, he calls him Francesco.
“A Maggot” by John Fowles. In this case, the word “maggot” refers to some sort of interrogation or sort of synopsis.
John Fowles is better known for his other opus work, “The Magus”, but this “A Maggot” was an interesting investigative read from different perspectives.
Oh! If you are looking for different perspectives, then the classic “Dr. Jekyll and Mr. Hyde” is a classic example of the same story from different perspectives.
Thanks for the recommendations and keep them coming.
Wanted to say it doesn’t have to be obvious “unreliable narrators”, just as long as they see things differently. I know there are a ton of intentionally ambiguous single unreliable narrator novels too which wasn’t really what I was looking for.
The Time Traveler’s Wife. Because mucking with time isn’t confusing enough.
Steven Brust’s Orca comes to mind. It alternates back and forth between two viewpoint characters. Trouble is, it’s deep into a very long series (projected 19 books; presently at 14) and while you probably could read it alone, or start the series with it, you’d be missing a LOT.
So, if you feel like reading a good half-dozen books to get to it, that’s one for you. 
Robert Jordan’s Wheel of Time series. It is hard to pick out in the first book, but becomes more and more pronounced as the series progresses.
And the mountains echoed is told from many pov.
The Expedition by P O Sundman is a (fairly short) novel, which is essentially a story told twice, chapter for chapter, from the respective viewpoints of two participants with different outlook and different cultural backgrounds. It’s great reading!
Lois McMaster Bujold has experimented with writing novels with multiple points of view. Bujold has a reputation for extremely good characterization and in my opinion has perhaps the most deft touch with point of view of any author alive.
Two novels come to mind. Ethan of Athos is told from two points of view, Ethan of the title and Elli Quinn. A Civil Campaign is more ambitous POV wise, written from four different points of view.
These are both science fiction novels written as part of Bujold’s Vorkosigan series. A Civil Campaign isn’t really a good place to start, it depends too much on having read some of the preceding novels. Ethan of Athos is designed as a standalone novel and is easily accessible to someone who has never read Bujold before. I think I ought to warn you that Ethan is homosexual, if that bothers you you might want to skip the book. There aren’t any actual homerotic sex scenes, though.
The Eternity Artifact by L. E. Modesitt, Jr.
It’s a pretty good science fiction story about an expedition to a truly alien world. Each chapter is told from the POV of one of the major characters.
It is well done, in my opinion, because you can easily pick who is telling the story by the vocabulary and the sentence structure.
The Private Memoirs and Confessions of a Justified Sinner by James Hogg does exactly this - it was written in 1824 and has 2 sections, one written by an ‘editor’ who describes a series of crimes from a relatively neutral point of view, and the other written by the religious maniac who carried them out.
Most of the books of P.C. Hodgell’s Kencyrath series do this. The first novel is from the point of view of one young woman, but the second introduces her twin brother. After that, the books switch between the twins’ viewpoints at varying intervals. The sister usually gets more pages, because she’s by far the more active (not to mention disaster-prone) of the two, but the brother gets into his share of shenanigans. Their relationship is complex, they spend a fair amount of time in each other’s heads, and both are often thought to be insane; there are scenes in which the point of view bounces between them quickly or is deliberately muddled.
A third major viewpoint character gets a little time in the later books as well, and will probably get more as his connection with the twins grows.
For Bujold, I’d recommend Mirror Dance as the book to read to see different characters’ points of view. It’s just two characters, IIRC, but one is a clone of the other.
Hey Nostradamus is told from the points of view of different people during and after a school shooting
I believe A Long Way Down is simultaneous (or part of it is) a tale of 4 people planning to commit suicide on New Years Eve running into each other and deciding to try to last a little longer
If you’re looking for a long series of novels, The Malazan Book of the Fallen by Steven Erikson does this a lot.
A lot of novelists use multiple points of view. As noted above, George R. R. Martin does it in A Song of Fire and Ice. Harry Turtledove did it throughout his World War series (and its sequels). Frederick Forsythe does it in his novels. In all of these cases it’s not a “Rashomon”-style situation, where each character puts his own “spin” on the situation, but simply a case of telling the story through different characters who might be best suited to explain different aspects. Heck, Bram Stoker did it in Dracula and Wilkie Collins in The Moonstone.
It’s got a long history, and while writing teachers might get bent out of shape because the author is destroying the Unity of Vision, as long as it’s clear whose eyes you’re looking through, I’;ve never seen any problem with it.
