More like your post got buried so I missed it.
One way to look at is is what's an angel?
The Outer planes that celestials call home foster an astounding variety of good creatures. Despite their great diversity, all celestials unite to battle fiends from the infernal realms or to assist lost travelers. Guardinals (neutral good) and eladrins (chaotic good) are invariably creatures of great beauty, though their appearances vary. Creatures they've helped on the Material Plane sometimes refer to them simply as “angels.”
As with the evil planes (as discussed in the Book of Vile Darkness), you can create your own cosmology of the good planes. You might prefer not to deal with the in-between planes of Arcadia, Bytopia, the Beastlands, and Ysgard, sticking with the planes that directly correlate to alignments. Conversely, you could have just a single plane of good, called Heaven, where archons, guardinals, eladrins, and angels coexist with little distinction among them (perhaps they are all called angels).
And if you include them, the Celestial breakdown is Archon (LG), Guardinal (NG), & Eladrins (CG). Sort of like Devils (LE), Yugoloth (NE), & Demons (CE).
But if you want actual Angels, as in the subtype, there are a few. The Solar is the highest ranking one while the Planetar operates as a general of forces. And Deva is actually broken down into three types & ranks. Movanic Devas are the weakest and they oversee the the Positive, Negative, and Material Planes. Monadic Devas oversee the Ethereal Plane and the Elemental Planes. And Astral Devas used
to oversee the Lower Planes and would attempt to rescue Good-aligned allies stuck in the lower planes. But in the Third Edition update they were moved to overseeing interplanar travelers. There was also a "Agathion" Angel and it appears they were 1st Edition & Planescape limited but otherwise function as Guardinals do in 3rd. PFSRD also seems to think this as their Agathion
list is composed of Guardinals.
The Movanic and Monadic Devas can be found under Deva in the 3.0 supplement Fiend Folio.
