Kara was 16 when she left Krypton, at the same time as baby Clark left. Her ship crashed undetected, so she probably arrived during the meteor shower. It took baby Clark around 3 years to arrive at Earth so Kara was around 19 when she arrived. However, she was then stuck in suspended animation for a further 18 years, but did not age. Depending on whether you want how long she has lived, which would be 37 years, or how old she has aged, which is 19 years. Hope that helps!

Yes, Kara is in Season 8 of Smallville however she's not a regular like she was in Season 7. She only appears in one episode in Season 8.
Tom Welling was 24 when Smallville first aired. He was born April 26th, 1977 and Smallville came on in 2001.
Lana became a less important character on the show. This season is mostly about Clark, Lex, and Kara.
There are different supergirls. Kara grew up on Krypton and was sent at the same time as baby Kal El. But her ship did not reach Earth until Kal El (Clark Kent) was an adult. She takes the name Linda Lee and is adopted in Midvale by the Danvers. There is another version where she is created by Lex Luther and goes to live with the Kents in Smallville.
