Can this adjust to punch 8 1/2 by 5 1/2 paper with 3 holes? (half sized)

You can adjust this hole punch to a number of sizes. It took me awhile to figure out, but I actually removed two of the five "punchers" and from there you can adjust the others to any distance you desire. I use mine to punch wholes in 8 1/2 by 11" paper cut in half for supplemental readings provided by my professors. In other words, the typical sheet of paper turned horizontally "landscape" and cut in half.

Will this punch 4 holes, 3.5" center of hole to center of hole? oooo outside/end holes 10.5" apart

Yes this punch can be adjusted to accommodate this setting.

How close together can you space the punches? i need 6 holes on 8.5" by 5.5" paper oooooo

The closest the holes can be is just under 1" center to center.

The home diameter of the punch heads always 11/32? Exist a a lower diameter?

The model 525M is the "medical punch" which has 11/32" holes. If you want 9/32" holes, select the 1325B. It is basically the same punch except it is black and has three punch heads. Up to 4 more punch heads can be added, part number 1025B.
