Yes. You can definitely launch multiple tasks within the same offer (launchTasks() takes multiple TaskInfos) as long as the sum total of resources required by the tasks (and their executors) can fit in the offered resources. In fact, if you are hoarding offers (not recommended if you are running multiple frameworks), you could use multiple offers in launchTasks() as long as the offers belong to the same slave.
