Play Operate Shooting Star but do not use Geo as a playable character as he breaks the balance of the game. There is no reason to play GBA BN1 for any reason at this point, it's completely pointless.
From there you either use the relocalization patches for 2-5 or play the Collection for 2-6.
Network Transmission is its own thing based on the anime and is essentially a mix of the anime and an OC retelling of BN1.
4.5 is an interim spinoff sort of thing. If you are going to play it then obviously play it between 4 and 5.
Battle Chip Challenge is this RNG-oriented autobattling spinoff which also had a Wonderswan version but the WS version has no translation. It's best to play it with the romhack that lets you pick chips because otherwise you just pray that you get good luck every single battle and there's no strategy outside of that.

Battle Network WS is a Wonderswan exclusive spinoff that plays sort of like Network Transmission but significantly more like Classic Megaman than NT's connecting hub sort of thing.
If you still want more then play Star Force 1 using the DX hack as this fixes up an insane amount of issues and functions as the Pokemon Yellow/Crystal/Emerald/Platinum for the game as it had three versions with the only differences being the form change and the Giga Cards.
Star Force 2 has a pseudo-DX-esque hack in "Not Quite DX" which does roughly the same thing for Zerker x Saurian and allows you to do a lot of stuff offline and merges the games together so you don't need to do three full game playthroughs or deal with Brotherbands.
Star Force 3 is fine as it is.
