Not sure what a strait line is! Five people can stand in a straight line, with Jessie third in 24 ways if you ignore left-to-right and right-to-left "reflections".
Five people can stand in a line in 5! (5 factorial) different ways. This is calculated as 5 × 4 × 3 × 2 × 1, which equals 120. Therefore, there are 120 different arrangements for the 5 people in a line.

There are 7 people who could stand first, with 6 people who could stand second for each of those first people, with 5 people who could stand third for each of those first two people, and so on, until with 1 person left who could stand seventh for each of the first six people. This gives 7 × 6 × 5 × ... × 1 = 5040 ways.
