Can i access all the servlet variables in all the service threads? does Synchronization play any role here?

Yes, instance variables would be available. In general this is a Bad Idea since Servlets are multithreaded and accessing instance variables would produce race conditions galore. Synchronizing instance variables to prevent race conditions, on the other hand, reduces the efficiency of multithreading.
