Hi Tim,
The tables from the column 9 (DYNAMICS) seem to be related to some 3rd-party product.. the others are common company table modules, but you should be extremely careful by not removing tables or content that belongs to “core” GP modules..
This site from a former Dynamics GP MVP (@Ian Grieve ) has a reference catalog for about 99% of the tables in GP company & System DB's.. https://gptables.azurecurve.co.uk/
This should help you identify the tables you're looking for.

PS: Column 6 tables look like a 3rd-party too.. BOMxxxx tables are related to MfG and Inventory, POPxxxx to the purchasing module. PCBxxxxx, RFQxxxx, POTxxxxx, seems all to be related to 3rd-party.. That's even more concerning if you haven't clearly identified which module they belong.
PPS: another excellent tool to identify tables related to GP forms is the GP PowerTools add-on. It has a resource finder that helps identify tables and fields inside of GP. The tool can be installed with a free 30-day trial : https://winthropdc.blog/gp-power-tools-portal/ (written by @David Musgrave MVP GPUG All Star Legend Moderator )
