The main theme park ticket will get you access to the safari.
I believe that if you pay the entrance you can enter in most of the attractions including Safari but you have to be sure that is open. If you want to go to another park like Hurricane Harbor (warter park) then is apart. The cost will depende if you are a member, if you have a coupon (you can find them on internet), if you buy for a group or solo and if you buy the ticket on internet vs on the park.
The safari is part of the Six Flags. It is no longer separate from the park. You ride on their bus/vehicle with a guide. There is no additional charge for the Safari just admission to Six Flags.
I believe you can have access to all the attractions with the season pass , but the best thing to do is call them or go to the website to verify.
Not sure. I haven't been there but I can find out. I have season passes. Not sure if Safari is included.
