Yes, they are so close, even today. The two them have said they get together all the time, and there are tons of pictures of the two together even this year, 2014. Billie has said she has a really close brother/sister relationship with David. Billie said this year that her son calls David "Doctor" when they met up together. Billie also gets along very well with Georgia Moffet, whose David's wife. David said once in 2011 after he was married, that he loves Billie dearly and always wants her for his own to Billie's ex-husband, Chris Evans. In the 2013 issue of Doctor Who magazine, when David Tennant and Billie Piper returned, the magazine stated, Billie and David were constantly laughing and hugging on set, David even said "I see Billie all the time.". Personally, I believe the two of them are as close as you can get before being in an intimate relationship. They are true best friends, both of them have said.
Yes, but not too close- Billie Piper is married to someone else.

No, they actually never went out, at the times they knew each other, they were with other people. Both of them have said they are currently (2014) best friends and get together all the time.
Some of his best friends are actor Adam James (appeared in the Doctor Who episode Planet of the Dead), assistant director Jennie Fava (who has worked with DT on many projects), and actresses Billie Piper, Arabella Weir and Louise Delamare.
I don't know why he wouldn't be like most men who find her very attractive.
Not really, no.
David Tennant is an actor. Time Lords are entirely fictional.
