I thought it was said that a Doppelganger had to be descended from the previous ones like Katherine and Elena, but Stefan didn't have children so how is he alive?

Yeah, Zach was Damon's and Stefan's half brother's child and it's possible :)
There were Salvatore descendants watching over the estate throughout the years, it was Joseph Salvatore that Damon killed on arrival at the boarding house in 53 and perhaps he had family so it will pass through a line not necessarily direct son of a doppelgänger makes a doppelgänger is too close and impossible.
The gene is in the Salvatore line but if the rest of that line is gone Damon and Stefan being vampire would possibly be the end of the Stefan doppelgängers and the same for Elena.
It could be half brother, and uncle line that has split from guiseppe but carried the line. Looking forward to maybe finding out more from the next episode.
Spoiler Alert!
Stefan previously had a relationship with a young woman named Rosalyn Cartwright, who was killed by Katherine because she was jealous. Perhaps both have had sex and fathered a line, or it could also be that Zach (which is the last descendant Salvatore believed) could have a child without realizing. I do not know, that's my hypothesis.
He doesn't necesarily have to be related to the Salva bros, considering Tom was descendant of Silas, who lived in ancient Greece. Just because both Stefan and Tom are doppelSilas, it doesn't mean they are close relatives.
Silas (or even his child/children) could have had more than 1 heir, leading to at least 2 branches of family, that throughut the milleniums became farther and farther away regarding bloodline. It's like saying that all the people with last name "Smith" are related, they might have been centuries and centuries ago, but not in the present day. And I think it's the same case with this Tom guy.

Zach could not be Tom's father, consiering their age. Zach was in his 30s when he died 3 years ago (according to the timeline). And Tom was obviously in his mid-late 20s.
