At the moment The Doctor doesn't have a companion. However his last companion was Donna Noble. In the recent Easter special 'Planet of the Dead' he had a one day conpanion Lady Christina de Souza. He doesn't want to take another companion, because of how he lost Donna and Rose.
Amy Pond is the Doctor's companion at the moment.
The eleventh Doctor will star in The Sarah Jane Adventures along with the third Doctor's companion Jo Grant, apart from that there are no plans to bring any former companions back to Doctor Who.

Matt Smith is the eleventh Doctor so therefore there have been 11 Doctors in cluding him.
The sixth Doctor's companions were Peri Brown and Melanie Bush.
3 doctors did - the 1st, the 5th and the 10th.
While those were the main doctors she appeared with, she was there in the Five Doctors (so she was with all the first five) and the Eleventh Doctor was in two episodes of the Sarah Jane Smith Adventures. So the answer is actually seven. :)

Sarah Jane Smith meets the Eleventh Doctor in the "Doctor Who" episode titled "The Sarah Jane Adventures: Death of the Doctor," which is the first episode of the fourth series of her spin-off show. This episode originally aired on October 15, 2010. In it, the Eleventh Doctor, played by Matt Smith, teams up with Sarah Jane and her companions to confront a dangerous alien threat.
The eleventh Doctor hasn't regenerated, he's only been in two series so far.
It depends. If you count the first two K9s as two separate companions, then the first and fourth Doctors tie for 9 companions each (not counting characters who were only traveling with the Doctor for one story). Otherwise, it's the First Doctor.
