The Black Cavalry, Red Cavalry, and White Cavalry in Qing Yu's year were three different armies. The Black Knights were Chen Pingping's team. They were one of the Qing Kingdom's most mysterious and powerful cavalry forces. They were famous for their surprise attacks from thousands of miles away and had very powerful combat abilities. The Red Knights were the Qing Emperor's exclusive army. They were in charge of the Qing Emperor's safety and the Jingdou garrison. Their warhorses and soldiers were donned in red armor and looked awe-inspiring.

There's no official rule saying they can't. Since fanfiction is a product of fan creativity and is usually not part of the official franchise control. So, they can probably watch it if they come across it.
Well, there could be a crossover where the villains from Dino Thunder and Dino Charge join forces first. This would force the Rangers to put aside their differences and come together. The Dino Thunder Rangers might be a bit skeptical at first about the Dino Charge Rangers' methods, but as they face tougher challenges together, they start to respect each other. And perhaps there could be a love story between a Ranger from Dino Thunder and one from Dino Charge in the fanfiction, adding a bit of romance to the action - packed adventure.
The Red Rangers from both teams would be really interesting. The Red Dino Thunder Ranger has his own set of skills and leadership style, and when combined with the Red Dino Charge Ranger's qualities, there could be some great clashes and collaborations. They both have a strong sense of justice but might approach situations differently.
Some kamen riders could be amused. They may see the creativity of the fans in creating unique scenarios. However, they might also be a bit critical if the fanfiction strays too far from the essence of their characters.
There could be many interesting elements in a Spider Riders fanfic. It might explore new adventures for the characters. For example, the riders could discover a new type of spider with unique abilities that help them in their battles against the Invectids. The story could also focus on the relationships between the riders, perhaps a new friendship forms or an old one is tested.
It depends. Sometimes stories labeled as such might draw inspiration from real events but could have fictional elements added for entertainment or narrative purposes.
