6 or 9....my guess is 9.

Sorry I don't have time to go through my thoughts on this except that the shortest and tallest are stuck and cannot move.

Let us assume that height of six people are 1,2,3,4,5,6.

Now arrangements:

1,2,3
4,5,6

1,3,4
2,5,6

1,3,5
2,4,6

1,2,4
3,5,6

1,2,5
3,4,6

Actually, since the number was small, I enumerated the possibilities.

i would also guess 5.
look at this way:-
1 and 6 are static. we are left with 2,3,4,5.
now the 2nd pos on 1st row and 1st pos on sec row can only be filled by 2 or 3.
using 2, i can fill in 3 different arrangements with 3,4,5 at the end of 1st row-3 ways
using 3, i can have only 2 arrangements with 4 or 5 at the end of 1st row-2 ways

since these 2 arrangements also account for simultaneous positions vertically and horizontally,
answer is 2+3=5.
