Not really. You're padding out your list to make it seem bigger.

How is that they are all Violet/Purple right?

4 are villains, 1 is one power on 2 different characters, and another is an incomplete power and a "Complete" version of the same power.
It's akin to counting Basco and Battlizers as additional red rangers.

Who and how would someone count Basco as a red ranger? Was there a part where he became an evil ranger like Enter did?

That was actually me derping. I intended to say Enter, but I got my villain names messed up.
My bad :lol

The first legit Violet hero in Super Sentai is Geki Violet. Nuff said.
*mic drop*

One of those Bad Guys became good in that armor before it was changed to red, the very first Violet Sentai ranger was Purple Orchid of Hanaranger or are we not counting Evil Sentai Rangers as Rangers?

Nope. All hail the violet muay thai wolf, the badass that started it all.

Shou Ronpo is a better violet.

Yeah but Gou/Geki Violet has moves like Tony Jaa. I will give Commander Dumplings his credits for being awesome commander of the year but even his badass Ryu Voyager cannot match the lethal bone-cracking attacks of Geki Violet.
