Solution:

Eight people: Jenny, Jessica, Juhi, Jasmine, Jerry, Joseph, Jonny, and Jimmy.
Years: 1964, 1957, 1985, 2003, 1990, 1979, 1996, and 1976. (The calculation is done for the present year 2021 → 2021 - 1964 = 64years)
1). Jenny's ageisaprime number.
31 is the only prime number, so Jenny's age will be 31years
2). The difference between Jenny and Jessica's age is a prime number.
The difference between Jenny's age and Jessica's age is → Case I: (31 - 18 = 13)years →13years;CaseII: (36 - 31 = 5)years → 5years.
3). The difference between Jimmy and Jessica's age is a multiple of 7.
The difference between Jimmy's age and Jessica's age is → Case I: 25 - 18 = 7years; Case II.I: 64 - 36 = 28years and Case II.II:57 -36 =21years.

		Person
Year	Age	Case I	Case II.I	Case II.II
1957	64		Jimmy
1964	57			Jimmy
1976	45
1979	42
1985	36		Jessica	Jessica
1990	31	Jenny	Jenny	Jenny
1996	25	Jimmy
2003	18	Jessica

4). The sum of Jerry and Juhi's age is a perfect square, whereas Juhi is younger.
Here Case II.I and Case II.II eliminate, As the sum of any age will not give a perfect square.
Case I splits into two cases; Case I 64 + 57 = 121 which is a perfectsquareof11 and Case I.II 64 + 36 = 100 which is a perfect square of 10.

		Person
Year	Age	Case I	Case I.I
1957	64	Jerry	Jerry
1964	57	Juhi
1976	45
1979	42
1985	36		Juhi
1990	31	Jenny	Jenny
1996	25	Jimmy	Jimmy
2003	18	Jessica	Jessica

5). The age of Jasmine is a multiple of 5 but her age is not a perfect square.
As 25 is a square of 5 but 45 is a multiple of 5.
6). Only one person is there in between Joseph and Jonny, who was not born in any even year.
The final arrangement:

Year	Age	Person
1957	64	Jerry
1964	57	Joseph
1976	45	Jasmine
1979	42	Jonny
1985	36	Juhi
1990	31	Jenny
1996	25	Jimmy
2003	18	Jessica

With alphabetical order:

Year	Age	Person	Alphabetical order
1957	64	Jerry	Jasmine
1964	57	Joseph	Jenny
1976	45	Jasmine	Jerry
1979	42	Jonny	Jessica
1985	36	Juhi	Jimmy
1990	31	Jenny	Jonny
1996	25	Jimmy	Joseph
2003	18	Jessica	Juhi

Hence, Jessica was born immediately after Jerry.
