I found the Hard Day's Night script in this website: http://leethomson.myzen.co.uk/Grey's_Anatomy/Grey's_Anatomy_1x01_-_A_Hard_Days_Night.pdf

It mentions that Meredith is 32, but she was said to be born in 1978, so is at least 28 during her intern, Derek is on his late 30s, Bailey 30, Burke in his 30s, and mentions Alex been 28.

Cristina is also 28 as seen in the OR Board

George died at the age of 29, so he was born in late 1979 or early 1980.

Izzie was 29 in S5, so  she was born in early 1980.

April and Jackson seems to be the youngests so they were 25 or 26 in their intern year

Callie says that her father was trying to throw out their 30 year relationship, so she was at least 30 that time and was born between, probably older because of the time that she spend on Peace Corp so she was born between 1976-1979 and is on her late thirties now.

Arizona in my opinion had to be at least 32 and no more than 35 in her first appearance so she was born between 1974-1977, so she is on her early 40s now.
