1. He was not a jinchuruki during his life. He only used the power while he was dead.
he became a Jinchuuriki the moment he sealed Kurama within himself. So you're wrong, he was a Jinchuuriki in his life time. He died after sealing the remaining half of Kurama into Naruto
2. He admitted his sage mode wasnt that good when he fought Madara. Dont overrate it.
Jiraya admitted the same thing, however his sage mode was still pretty darn good. And Minatos sage mode surpasses Jiraya's since minato is a perfect sage. So again your comment is rubbish.
3. When he fought Ay and Bee,yes he could have easily won the fight but lets not forget the sword Bee had pointed at him at the same time. Stalemate.
he was never aiming to kill bee in the first place, it was just a warning. Bee was still marked, so minato could've teleported right in front of bee if he wanted to. Fact is minato could've killed them both if he wanted to.
4. He does not have RasenShuriken or any other variation of rasengan. Didnt love long enough to master it.
He can make bigger sized rasengans just like jiraya and Naruto can. Different sizes equal different variations, so again you're wrong 
5. His ftg IS the fastest s/t ninjutsu in the series. Proven when he teleported to the battlefield before Tobirama and the others.
idiot, minato used body flicker to get to the battlefield, how could he use FTG when there were no markings. If he used FTG, he would've brought all the Kage with him as well moron.
6. He did not singlehandedly beat the 9 tails. He had the help of the village and Kushina.
He could have. It's just that fighting Obito and then having to teleport Kurama exhausted his chakra. Minato was going to out a barrier up and then perform the sealing, but Kushina offered to instead.
7. His natural speed& reflexes are incredible. Need to be to fully use ftg.
first thing you've said that is right. Although your grammar is bad in the second sentence, so I'm not sure what you're trying to say.
8. His ftg is essily countered by someone with superior footspeed. For example Ay reacted to his Ftg almost instantly.
ay did not react to his FTG, minato was about to slash Ay in the back, as a result of this, Bee had to save him.
9. Minatos chakra nature is unknown. So theres no use trying to give him RasenShuriken. Its a wind style move. When Kakashi tried to mix lightning with it, he created chidori. So lightning& wind are out.
yes his chakra nature is unknown, all we know is that he has one at least
10. His edo feats should not be counted in battle. Edos have unlimited chakra and regeneration, which you dont have in real life. Also, he didnt have bm or km during his life.
his Edo feats can be counted because it's there and it exists. If you don't want to count it then that's your problem. However if other people to, then there's nothing you can do about that. Feats are feats, whether he was alive or not.
