She is trained, mostly by other priestesses, but there are also monks, in the lore of the great underground labyrinth into which only she is allowed to go. Before the entrance to the labyrinth proper is a ...

Consider this photo of Eddie Cochran:
Compare that with a crew cut (1943):
Heinlein doesn't mean Beatles long.
He means rock star long which was still much longer and puffed up than the average well-dressed business man of the age.
This sounds very much as though it could be The Zero Stone by Andre Norton (which also has a sequel - "Uncharted Stars"), first published in 1968.
The young man's name is Murdoc Jern and he has an alien companion, kind of like a cat, called Eet.
One of the most familiar covers (at least to me) is:
There's a reasonably complete write-up by Judith Tarr on the ...

This is James Tiptree Jr.'s The Starry Rift .
From Publishers Weekly:
The unsettling quality one expects of Tiptree is immediately evident
in the sequences framing these three stories that share the background
of the pseudonymous novelist's Brightness Falls from the Air. In a
prologue, a librarian in a great galactic library and two students

This is a trilogy by Tripods author John Christopher: The Prince in Waiting, Beyond the Burning Lands, and The Sword of the Spirits. Literally everything fits, except I don't think the sword mentioned in the last title was blue. It was made in a modern-style blast furnace of case hardened steel, by the high seers who lived hidden under Stonehenge. The ...

The main character had was a girl with the "long-forgotten job of being a guide." Check. She’s a Farwalker, who used to carry news and so forth between villages.
When she told him, he mused, “There aren’t supposed to be any
Farwalkers left. Storian told us in class that ...
This is The Lotus Caves, by John Christopher, published in 1969.
It's tied with The City of Gold and Lead for my favorite work by Christopher (a.k.a. Samuel Youd).

Pretty sure that is Piers Anthony's Race against Time (1973).
Some details to help verify:
He lives in a town which is done to LOOK like Nebraska, but isn't.
He has a dog that seems to have capabilities beyond what a dog should have.
Adults are actually a medium color, but spray themselves to appear Caucasian (in his area. Different colors are used in the ...

passersby please take notice!” the tall man was saying in a piercing,
nervous tenor. “This man, Harvey T. Gonno, is ill with an ...
I'm pretty certain you are talking about The Golden Compass by Philip Pullman. It is part of the His Dark Materials series, which include Northern Lights (called The Golden Compass in North America), The Subtle Knife, and The Amber Spyglass. Fantastic series.
"The Ice Warrior" by Robin Chambers is likely the story you're thinking of. It has the barefoot Zaire kicker, the frozen ball, a grave where there was always snow even in summer (I know... a reversal of what you said), and then some other mysterious goings-on such as the people who set up the frozen ball dying in ice-related ways.
It looks like it's only ...
