I believe he was born in 1981, which would put his age at an estimate of 27. However, it isn't clear how long he traveled with the Doctor, so there may be another unaccounted for year. We're also assuming that The Doctor's time with Donna was about a year as well. And since the Parallel world runs faster then this one, he could be 29. So some where between 27-29.
103?
If you mean how many Doctor's - then eight in the old series, and three so far in the new series (though the actor playing the eleventh doctor is due to be announced today). There have been hundreds of separate characters.. I'm not sure about the old series of doctor who, but some of the main characters in doctor who in the previous series (2010-2011) are: the doctor rose tyler Martha Jones Donna nobel captin jack Sarah Jane smith and many more....
