From the information given, there are a total of 8 dance items.

It is given that the first performance was by Princess and it was composed by Badal and the last performance was by Rani and composed by Gagan. No dancer performed her second item before the performance of the first item by all the other dancers and the dancers performed their second item in the same sequence as their first.

Therefore, the fourth and the fifth performances are by Rani and Princess respectively.

Items assigned by Ashman were consecutively numbered. Because the first four performances were by four different composers, the only possibility is that Ashman composed the fourth and the fifth performances.

If the sixth performance was composed by Badal, then the seventh would have been composed by Dyu. It is given that the number of performances between items assigned by remaining composers is the same. In that case, performances two. three and four would have been composed by Badal. Dyu and Gagan, in that order.

If the sixth performance was composed by Dyu, then the seventh would have been composed by Badal. In that case, the number of performances between items assigned by Badal is 5. Therefore, the number of items assigned by Dyu should also be 5. But that is not possible.

Therefore, the second, third, sixth and seventh performances were composed by Dyu, Gagan. Badal and Dyu respectively.

Since no composer who assigned music to Princess is assigned music to Queen, the sixth performance cannot be by Queen. Therefore, the sixth and seventh performances will be by Samragni and Queen respectively. Since the sequence is the same for their first items as well, the second and third performances will be by Samragni and Queen respectively.

Therefore, the overall sequence will be as follows:
