Copying all the data elsewhere and re-partition is still the right answer…
You could possibly get away with copying the data out of the last partition, deleting the last 3 and extending the other one then copying the data back but, as others have said, you seem to have rather too many partitions.
ETA: there is no way to merge ntfs and ext4 partitions anyway - even without the intervening partitions that are present here. Copy, destroy extend is the only way.
