Which reels to keep?

I used to fish, up to about 25 years ago. I kept 3 rods, a box full of reels, and everything else went.

The 3 rods I have are…
Masterline 9’ John Wilson Stalker
An 11’ 6 Warrior Bass Rod (was a gift from a dearly departed)
Shakespeare 10’ Mackerel feather rod

I live in the midlands, have a van that gets used for days out, regularly stop in wales by a lake, and maybe min 4 times a year get to the sea.

What I want to do is have a set up that lives in the van, with the Stalker rod paired up with one or two reels, so that if I’m by a river, a lake or by the sea, I can get some use out of the rod.

The reels are where I’ve lost the plot. Please someone remind me what’s what, what to put on the van, what to take to the charity shop.

There is:
DAM quick Mega 130, 1 spool, think this was my first reel as a kid
Shimano Carbomatic GT4000, 2 spools
Shakespeare Mustang 2150 040, 3 spools
Shakespeare Cosmos 2002, 1 spool
Shimano ST6000RA bait runner, 1 spool
2x browning 412 composite, 4 spools in total
Shimano SSG 3500M, 3 spools
