Post the Second!
For 6, he could spend any amount of time between dropping Mel off, having his own adventures in Big Finish, picking Mel up, and dying death by Rani. I'm going to guess around 1000 years due to him not looking so different, from what we see from McCoy in a wig. COuld be almost anything, though. (Total: 6310.)

7, again, has lots of Big Finish aventures I'm not aware of. However, due to his lack of a companion in the movie, plus his advanced age, probably puts him near the end of his life. This also sits with him just relaxing in his TARDIS, doing errands for the Time Lords instead of getting involved in adventures. I'm going to say 1200 years. (Total: 7510.)

Eight, just due to the sheer amount of stuff (including around 800 years on Orbis, apparently, plus some time spent not aging in the Anti-Time World, plus attempting to avoid the Time War, plus looking very lightly older in Night of the Doctor, means I'm going to say the full 1300 years for him. Or more. I honestly don't know, Too much confusing time stuff. (Total: 8810)

Nine has very little time without Rose in series (Before Rose and during that bit at the end of Rose is all I can think of.) However, due to him saying he's 900 in THe Empty Child and War being about 800, I'm going to say he's 100. (Total: 8910)

Ten really didn't live long. He gives his age as 910 in The End of Time, which is merely 10 more than Nine. EVen taking the end of The End of Time, that's still not long, working out at 10 living 10 years. Maybe that's why he really didn't want to go- he was nearing the end of his regeneration cycle, and he'd used 0.8% of this bodies full lifetime. (Total: 8920)

This means the Doctor is probably around 8920 in Deep Breath. Add on a year or two for time without Clara, and we get a total age of 8921... ish. Let's see how long it takes for people to pick massive glaring holes in this
