Hello NewB,
Top one is the request (..41) and the below ones (..42 and ..43) are tasks. Tasks change according to the username.
When you change a program system automatically creates a request and creates a task for that user under the request. If another user puts objects in the same request another task is created for that user also. You can manually create other tasks under a request. You can delete unwanted tasks. If you delete all the tasks you can delete the rewuest too.
Deleting and creating is up to you. Main focus is the chnage you want to move to other systems. If you want th changes in qa and prod systems you must keep the tasks and requests. If you donot want to move them to qa and prod you can delete them.
Deleting task or request means you delete the locks on the changed objects. So other developers can change these objects and carry your change and their change together ro qa.
Deleting task or request does not mean that the changes on objects will be deleted. If you changed an object and donot want to move the changes to other systems you should revert back to changes on object before deleting the task or request. Otherwise as I mentioned in previous paragraph someone can move your unwanted changes to qa and prod together with his/her changes.
