If you want to reclaim the 102GB of free space you will need to use the Disk Utility GUI (click on the Partition tab) and see if it can be merged into another partition. You don't have a choice in which partition it can be merged into since that free space can only be merged into the partition that is immediately next to the free space. Unfortunately the layout you have listed doesn't necessarily show which partition is closest to the 102GB of free space.

Sometimes you just need to start over from scratch by completely erasing the physical drive and re-installing macOS and creating new partitions.

The difficulties you are experiencing is one reason I do not recommend anyone to use multiple partitions on a drive since sooner or later the user will want or need to resize them or get rid of one which is no longer needed. Modifying partitions is always risky and even unpredictable.
