I am new here and wondering if any of these rocks have quartz in it ? I think the one in the middle is but I am not sure. I am not too sure what rocks are good indicators of where to pan for gold or which rocks to smash for it. I took these from numerous spots on the bend of a stream. Can you please tell me if any of these are good indicators ? Also one of the rocks has some black spots in it. Any idea what it may be ? Thank you !!

Quartz is one of the most common minerals on earth. There's a bit more to it then just looking for quartz. :)
Look for quart veins, lens-shaped quartz bodies for example. Rust is another good indicator to sample the rock, of which I can see at least 2 in your pictures.

Most of the rocks in your pics look quartz-related as in the form of chalcedony.. A low temperature variation of quartz.

I went ahead and broke the rock in half. I am curious as to what the black parts are. There are also a lot of shiny glittery pieces in there. Some of the glittery pieces are in some of the black pieces. What can that be ?

They seem to be "haloes" around cavities. Sorta like a lining around the cavity.

I created a rock project with this rock, and would like to know what it is so I can include it with the gift. Thanks.

Show me a chipped edge or something freshly exposed. Cut, sawed and polished rocks are near impossible to ID from a mere picture.

I put some in muratic acid and I could tell it contains sulfides ....

I'm not sure most sulphides react with muratic, but I suppose it depends on the concentration of the acid.
Usual "testing" for minerals is 10% Muratic and will not attack any sulphides I can think of.

Close to a fire place? Low or high conductive? I've seen similar things that were melted aluminum cans from campfires.

See attached picture of original uncut rock, approx. 3x4". View attachment 1412210

Well, it's a hydrothermally altered rock. I can't with certainty tell if it might be a metamorphic rhyolite, jasper or something similar.
It's one of the "see it in person" cases to make a qualified guess.

Is the first one really that yellow?
But, no I don't see any gold. I'd suggest you look for the gold, since it's your rock. Crush and pan some!
I'd love to see the rock-exposure where it came from. The host rock looks "granitoid" like, which makes it more likely to find silver there in my experience.

Look for rusty or discolored spots, fracture-zones, veins of any type and contact zones...
Anything out of the ordinary is sampled, take some time to get acquainted with the "normal" in the close-by area.
Learning the normal is simply a matter of hiking around and about and soaking in the "look"(/type) of rocks present, be observant.
