(3) If yes to my second question, non of the Q acoustics ceiling speakers come with back cans or back box enclosures. Is a back can necessary for better performance of ceiling speakers. Thanks for your anticipated responses
I will leave the tweeter question for others to answer, as I myself haven't tested them, but as the tweeter ranges are very directional, a dual tweeter will help the sound to reach two different locations. Quite helpful if you have multiple rows of seating, but I can't see them as helpful when you have four speaker layout (x.x 4) instead of two (x.x.2). Are they individually aimable? If not, I would not.
If the speakers are timbre matched then yes. Verify with Q acoustics tech advisors. It seems the speaker you mention is the in-ceiling "stereo" speakers. No, you must not get the individual stereo speaker, as those are meant for a speaker that performs the duties of a dual speaker. Instead, you should buy two of the mono speakers, such as the QI65C.
I was initially concerned with back enclosures when I got mine, but my tech advisors suggested against it. Back cans are not necessary, and sometimes will make your life more complicated because of unwanted side effects, say resonance flutter, speaker contact buzzing etc. Dynamat for example touts reduced sound migration to other rooms as one of its prime selling feature for the enclosure, so if its not important, I say don't do it. Let Q acoustics advisors chime into it.
Hope this helps.
