Changing Partitions With GParted

Dual Boot, two drives with four partitions. I need to increase the Linux paritions on the both drives and double the swap parition. After playing with GParted, I can't figure out how to increase the Linux parition as the "resize" button is always disabled (see the screenshots). Not only the current login Linux is not resizable (that is right to my understanding), but the other Linux parition in the other drive. And the swap parition isn't resizable either. The current sign-in parition is that one with 931.51GiB. What is the right way/process to make the parition change?
