Yes, you could delete and recreate the last partition in the table, but 
this sounds like a lot of extra (unnecessary) work.

Any interaction with partitions can result in loss of data, so a fresh 
backup at least of the partition table before you start any resizing/
deleting/creating partitions is advisable.

I suggest you unmount partition 5, then use parted (or if you prefer a 
GUI try gparted, or the KDE Partition Manager) to resize the end point 
of it.  If you use parted on the CLI you will additionally need to 
increase the size of the filesystem within the partition after the 
partition has been resized.
