Multiple objects travelling in paths and hovering while emitting intermittent sparks and/or flames

Upon taking our dogs out for the evening, I spotted a glowing light in the northeastern sky. It was white/yellow in color and was moving in a meandering path to the South. While I viewed that one, I observed either flames or sparks coming out of the back or bottom of it twice. Just as the object passed over our roofline, I took the dogs in and called for my fiancee to corroborate the sighting. She immediately came outside, but by that time the object was not viewable from our backyard. As I started around the side of the house for a better view of the southern sky, she called me back, saying that 3 objects were now visible in a roughly NW direction.

I got back in time to witness all 3 of these objects one at roughly 290 degrees magnetic and the other 2 at approximately 310 degrees magnetic. One of those 2 seemed to be slightly lower and to my right of the other, but since they looked to be far away I was unable to determine how close in proximity they were to each other....one could possibly be lower to the horizon than the other. She also stated that these 3 objects emitted the same phenomena that I witnessed with the first object, but they did not do it in unison. She stated to me later in the evening that at least one of the objects got close enough to our home for her to see that it was roughly triangular-shaped.

I immediately ran inside for my phone, and by the time I returned only one of the objects was visble (I found out later on that the 3 we observed had ascended into the sky and vanished, and this was in fact the 5th similar object). This one emitted the sparks/flames as well, but only once while I viewed it. By the time I pulled up the camera app on my phone, it was already beginning it's slow ascent into the night sky, where it eventually vanished like the others that my fiancee observed.

Neither of us heard any sound at all coming from these objects, and we could not explain their appearance due to a) there was no evidence of blinking lights as you normally see on an airplane; b) they all appeared to hover momentarily in their movement, which planes cannot do; c) despite the fireworks being shot off in the neighborhood, we are both very familiar with helicopter sounds and as I stated previously we could not discern anything sound at all coming from them; d) I don't believe they were drones...being a drone owner myself I have yet to see a commercial product that is capable of carrying a payload heavy enough to emit sparks/flames even once, much less multiple times as was the case with the first object I sighted, and these objects ascended before vanishing rather than landing, and finally; e) there is no possible way they could've been fireworks as the first one followed a path across the sky without descending, and the footage I was able to capture shows I had th! e final object in view for over 1:19 minutes - which no type of firework is capable of sustaining.
