From the first line we can see that the A comes before G. Therefore, we can assume and randomly put G's birthday in the month of April.
1. According the the first hint, we can put A's birthday in March.
2. From the second hint we can put C before A. Therefore, C will be placed in month of February.
3. Then after referring to the 4th hint we can place E in the month of June as after 2 months of A 1 is a blank month and G is 1 month after A. As the age of E is 45(given in 3rd hint). The age of G will be 50 and the age of A will be 40 as in 1st hint it is stated that age of A is less than 50 years.
4. There are 2 birthdays between E and D. Therefore, we can place D in the month of September.
5. From the 5th hint we can place B in July and F in August.

From the above given resolution, we can answer the 3 questions as :-

1. A
2. F and the other we cannot determine due to insufficient data.
3. age difference is 10.

Persons in order : | C | - | D | - | A | - | G | - |-------------------| - | E | - | B | - | F |
Months In order : |Feb| - |March| - |April| - |May | - |BLANK Month| - | July | - |Aug| - | Sep|
Age : | X | - | X | - | 40 | - | 50 | - |-------------------| - | 45 | - | X | - | 69 |

Logic :
=>Using S3 age of E is 45, now using S1 and S4 we can find out age of A, G as well as positions of A,G,E and Blank month.
=>As we know the position of G then, using S2 we can put C, as well as Using S3 we can put D
=>Now you can put B and F at 2 locations, so seq will like

CDAG[Blank]EBF OR BFCDAG[Blank]E.

Also you can put the months based on this arrangements as per your convenience.

Answers based on my arrangements :
Q1 : D, Q2 : F and any from[CDB] , Q3 : 5 years

3. C ,A ,G ,E ,B ,F ,D (Feb ,mar ,apr,"gap",june ,july ,aug ,sept)
4. C ,A ,G ,D ,B ,F ,E (Feb ,mar ,apr, "gap" ,june ,july ,aug ,sept).....not apply becoz of gap condition( G-D # 5)

values:- E=45,F=69 ,A=40,G=50(acco to 1st and 4th cases)
