How much is the receiver power output if (4) 6-ohm speakers are used vs (2) 6 ohm speakers?
Sidenote: Technics and Onkyo used to be the gold standard in home stereo components with Onkyo being in the upscale side. Now, Sony, Yamaha, Pioneer and Sherwood are common brands.
For tuner/amp power output, 100 watts per channel used to be par for the course and I think it still is.
IMO, Sony and Sherwood would be on the lower side for home audio.
There are many brands out there and people just have their preferences.
I'm sure Sony has some high end stuff but their quality may have done down. That's not to say it's junk.
I prefer Yamaha and have for years. They have some really high end stuff, some mid-range stuff but not low end.
There's Denon, Onkyo, Harmon Kardon, and many more. Marantz is known as a high end brand and so are others you never heard of. They prefer quality over quantity and the price shows it.
As far as the ohms go, the lower the ohms, the more power they draw from the amplifier. 6 ohms is not that common, I usually see 4 or 8.
Stereo units only have two channels, so the question about 4 speakers does not apply. As you will see in the specs you listed, it states 2 channels.
100 watts per channel should be adequate for Stereo. With 5 or 7 channel amplifiers, you would typically get 100w x 5 or 100w x 7.

I am interested in possibly in starting out with two speakers and adding two more (or a subwoofer) later.
I will need to pay attention to the electrical specs on the speakers as well.
I want to make sure the initial receiver has the electrical specs to handle what I might add on later. Is it true that most STEREO receivers can handle at least two pairs of speakers? Many have connections on the back for both A and B speakers. Some have a subwoofer connection as well. I think it's important to buy stereo components that are a good match.
there is no correlation between resistance (4 vs 8 ohms) and quality; amps output more power, up to a point, with lower resistance speakers. (good amps are usually rated to show both, and if they have a good power supply, you'll see the number double for each halving of resistance up to a point) most consumer grade receivers you'd see at best buy don't have a good power supply. (expensive internal components like a big transformer)

Just match it to what is recommended by the manufacturer of your amp. Usually it says on the back of the amp next to the speaker connections. There may be different connections for different speaker impedances.
impedance is the measure of resistance at a given frequency, the rating of which is a general figure. your hair splitting has contributed nothing to the conversation at hand, thank you and good day.
Pick your speakers first. That way, you can buy a receiver that can properly power your speakers. Onkyo is a former of itself. They aren't as reliable as they once were. I gave up on Onkyo receivers after owning two of them and they both broke down under 2 years. One was low end, the other was midrange. Thank God I bought warranties. My low end Harmon Kardon is 12 years old. My mid range Marantz is 14 years old. Both still working to this day. If you want Onkyo, get their higher end brand, Integra. I like Pioneer Elite and Yamaha Aventage.
Honestly it doesn't matter. The speakers impedance varies with frequency. An amplifier has to be able to deal with a dynamic, ever changing load (impedance). A good amp can supply proportionally more current in response to a low impedance in a linear and predictable fashion. The dynamic ability to supply current on demand is what makes a good amp. Not the steady-state power delivery....
