I'd say with about 95% certainty we're looking a one more female in Violet. But that color is just ambiguous enough that they could go male with it. Gray is more of a sure thing for male. Silver it a tossup though. I could see silver going either way.

Considering the only other violets were male (That being GekiViolet and, should Shockercon be believed, Wolzard), and taking their Yellow statement into mind, KyoryuViolet isn't set as female, and actually has a greater chance at being male.

Wolzard doesn't count, he wasn't a sixth.

magishine is 6th and wolfazrd is 7th and magi mother is 8th

Wolzard was an other, so was Magishine. If there was any real 6th ranger it was MagiMother/White Ranger.

No Shine most definitely fills the role of 6th in Magiranger. Mother was so infrequently used that she's like Dekamaster, an extra ranger.

Yet! Shine was one of the Other Rangers used by Basco.

He was one of the Sixths used against Marvelous and the others. Basco used Wolzard Fire and MagiMother after Gai joined the team, along with SignalMan, DekaMaster, DekaSwan, Rio, Mele, Zuuban, and Hime ShinkenRed- the Other/Extra Hero Keys.

Edit: And Den-O, we kinda already know what #9 and #10 of the Zyudenryu are:
9 – Plesion (Plesiosaurus)
10 – Bragigas (Brachiosaurus)

Okay. And your point? He's the 6th ranger, there's no question about it. And he's on Silvers Gokai Cellular too, which is all about 6th rangers. That's if you need some Gokaiger evidence

Yeah but there was no confirmation previously that they would have mecha until today.
