Triangular craft, later 2 orbs

Date: July 3, 2022
Time: 5:15 PM
Location: Seen from our backyard (42.1689984 , -71.215252) while laying in a hammock.
Direction: Easterly, around 54 degrees N-E. The second sighting of this object was around 60 degrees N-E (about 45 minutes later).
Sun Location: Behind us
Weather: Clear blue skies
Witnesses: 2 (Me and my wife)
We witnessed this while laying in the hammock in our backyard watching birds and planes fly by.
Shape
Difficult to define an exact shape, perhaps a right-angle isosceles triangle. It almost looked like a large bird at first, hovering in place as they can do in a heat vortex, but this object was larger and we couldn't reconcile its exact shape, size, and color with any bird or vehicle, especially as airplanes and jets flew across the sky at the time of this sighting. When I first noticed it, I said to my wife, "Look at that hawk way up there hovering!" but immediately second-guessed my idea that it was a hawk or large bird because it remained motionless.
Color
Edges appeared a bit fuzzy at first but then became sharp/more defined. Blackish, dark red while it was hovering. When moving, silver and white in color, streaking across the sky at an incredible speed.
Additional notes
Almost the entire time I was wearing polarized sunglasses. When I took them off, I could still see the object. With the glasses on, it lost its dark red hue and looked more charcoal than black. This object was hovering for a few minutes, staying almost motionless as a jet flew over its vicinity. When the jet moved further away, the object, in a very fast sequence, appeared to tilt or turn, then appeared cylindrical in shape, losing its black/dark red color, and like liquid-silver & white streaked across the sky with incredible velocity. The steak was only visible for a second and the object was gone.
About 15 Minutes Later:
A white orb, extremely high up, traveled across the sky from west to east. I could not see it without my sunglasses on.
About 10 Minutes Later:
Another white orb, perhaps even higher (or smaller in size), traveled across the sky in the exact same way (west to east). Both of these orbs couldn't be seen without my sunglasses on and they shared the same characteristics (constant speed, no wavering or anything, appeared solid and spherical, soft-white in color, and perhaps illuminated only by ambient light, traveling west to east).
45 Minutes later:
The original object appeared again but not in the same position. Black in color this time. Hovered for a minute, then moved slowly out of sight to be obscured by our treeline. The total time was about a minute, maybe less. I'll note that both times we didn't see where this object came from.
