Four bright orange spheres drift randomly above tree line then head north, fading as they go.

At about 10:20 PM on May 21, 2021, I stepped out on the porch on the west side of my home. A light in the sky, just above the tree line and due west, caught my eye. A few minutes previously a small plane had passed by, also due west, moving from the NW in a southerly direction, with the usual running lights and strobe. This, however, was a bigger “blob” of light, very orange, basically spherical but not perfectly so, randomly changing in intensity. It drifted from NW to SW, continuing to “pulse” arhythmically. There was no sound at any time. After maybe 10-15 seconds three more lights, very similar, all orange, drifted in from behind the treeline. They all traveled around lazily, with random changes in velocity and slight changes in direction. All orange and very bright, sometimes dimming slightly or appearing to go translucent. They didn’t settle into any particular configuration, and never too close to each other. All remained just a few finger widths abov! e the treeline, then all four began to drift north.
 At this point I dashed into the house to get my husband out of bed. He hustled out with me but the lights had gone. After a few seconds a single one drifted up from the treeline WSW of us, then headed NW, again very slowly and with a sort of jerky, random velocity change movement. It faded out as it passed to the north.
 The whole sighting lasted maybe four minutes.
 I have phone video but it’s not very helpful. I’m attaching an image I made in Photoshop which more accurately depicts what I saw. These were not satellites. There were wispy clouds and these objects moved in front of the clouds.
