Blue Centurion and Phantom Ranger could be considered rangers ?

... Phantom Ranger literally has ranger in his title. Blue Centurion is more debatable but I think the general opinion is no, both considering th fact he never morphs, and his equivalent is considered an extra hero by Gokaiger

Should Phantom ranger be called with another name ?

Should the Alien Rangers be called with another name ?
Should the Green Samurai Ranger be called with another name ?
What does that question even mean?

I don't know, this name make a lot people confuse with Power Rangers.

But... he is a Power Ranger.

What if they relaunch all the Megazords for the next anniversary season ?

As toys?
Then Bandai will be blowing a whole lot of money in one go.

Could you please... PLEASE detail/word your questions in a more concise/understandable manner? Are you talking about in the toyline or in the show?

I'm not convinced Sevenlima is a native English speaker, or is very young. His questions and posts come across as really incoherent and difficult to extrapolate.
