Yes. During the series we have been introduced to many Time Lords, from The Monk in "The Time Meddler" through to the half-Time Lord River Song (as revealed in "A Good Man Goes to War"). He travelled with at least one Time Lord, Romana, or two if his granddaughter, Susan, was also one. We have also seen many Time Lords on the Doctor's home planet, Gallifrey. The 2005 episode "The End of the World" revealed that the Time Lords were all but wiped out at the conclusion of a great Time War involving the Daleks, "Dalek" reveals the Doctor did this. Nevertheless, it is known at least one other Time Lord, the Master, survived ("Utopia") and the Master was later manipulated into allowing the Time Lord leader Rassilon and a group of Time Lords to briefly escape the time lock around Gallifrey before they were returned to their proper time.
The series is not consistent as to what a Time Lord is. The original series suggested it was a title earned through attending an academy. The revival series (in episodes such as "the Doctor's Daughter", "A Good Man Goes to War" and "Let's Kill Hitler") has established "Time Lord" as a species (with references made to Time Lord DNA, for example). If so, then the most recent Time Lords seen in the series are the two Gallifreyan museum technicians and Gallifrey Clara in "The Name of the Doctor" (assuming the John Hurt character is in fact the Doctor and not somebody else).
