{in the mean time I believe the answer is that five students can be seated 120 different ways and still be "in circle" as you requested.}

That would depend on what you mean by "five inch circle".
Just like a clock face: 12 students.

It is: 5/8 of 360 = 225 degrees
It depends upon how many students are talkative. I'll give you two examples. 0 students talkative - 1 way 1 student talkative - 15 ways
About 200 billion.
The answer is 17. If you draw a circle and put student 8 at the "3 o'clock" position and student 16 opposite at the "9 o'clock" position this will set up your circle. That means there are 7 children (9-15) that are evenly distributed in the bottom half of the circle. This will put student 12 at the "6 o'clock" position. Making sure to account for students 1-7 you'll have to put them in next. This will put student 3 at the "12 o'clock" position. This leaves three slots left in the top left "piece of pie". Students 1 & 2 go there along with student 17. 17 students will be evenly distributed around the circle with student 8 & 16 opposite each other.
