You've just started and you've got Apollon and Poseidon? I don't think we have enough testing on them to be sure of their abilities, same with Rapid Eagle.
As for the others, Trygator is more of a collectors bey (as are the three I mentioned before), and isn't very useful. Master Driger has a very fragile AR but I guess the SG Semi Flat Base is useful, use torch pegasus's AR with that and the heaviest WD and SG you have (probably 10 Heavy for the WD and I don't know about the SG's of the other beys), for some kinda compact.
Driger G has a great AR but you don't have any good attack bases, and it's own base is an engine gear one, thus too tall for anything really.
Bump King is basically the worst beyblade, and the AR is really fragile. I guess you could use it with Torch Pegasus' AR and 10 Wide (if you have one) to make some kind of survival type but it wouldn't be as good as the compact thing I mentioned before.
Apollon and Poseidon both have aggressive AR's but as I said, you don't have any good attack bases, and they're very valuable so you may be able to sell them and buy more useful beys with the money, or keep them for collection rather than use them. I mean, I'd want to test them out but yeah.
So overall your best combo is gonna be
AR: Torch Pegasus
WD: 10 Heavy (or 10 Balance if you don't get a 10 Heavy)
SG: Neo Right SG (HMC (which you won't have) > MG Core > Metal Weight Core), or if you have none of them, just a regular SG.
BB: SG Semi-Flat (Master Driger)
jan: Torch and Flame Pegasus are the same (just hasbro/takara names respectively) both of them have the gyro gear thing that sucks horribly, but the AR is nice. And you confused Apollon's AR with Poseidon's, no one has really tested Apollon's, haha.
