Absolutely no. Zira is Vitani's biological mother. Any 视频 that 显示 things like that 或者 anything that has to do with a non-Disney character that isn't from the film is 100% fanmade. That's just made up 由 someone who believes in a different story line that filmmakers did not add to the film. Many 粉丝 believe some characters (especially those from outsider 图书 'TLK: SNA') that are NOT 迪士尼 creation, exist in the film rather than following the true canon.
Anyway, the cub in The Lion Guard is Kion but Kion isn't Fluffy. Fluffy will always be genderless 或者 Kiara in the film alone. TLG is only a spin-off 显示 for kiddies under 10 yrs plus, the 显示 doesn't connect to the original film 或者 the sequel. In the film Kiara will always be Simba's only cub. TLG is clearly not canon to TLK 或者 TLK 2. But, still Official to 迪士尼 with a whole different story line.
Kion is Kiara's little brother only in the alternate movie universe, 迪士尼 already labled Fluffy and Kiara as one character and not turning Fluffy into someone else. Fluffy isn't anyone except Kiara. The creators of TLK 2 has clearly decided for Fluffy and Kiara to be the same. Kion is a newly character that only exist in TLG and TLG is not connected with the films. So, Fluffy is still Kiara in the two films and Kion is only a alternate character as Kiara's younger brother.
In a way, I'm glad that TLG isn't canon to TLK 2 because I seen it once and didn't like it. the 动画片 is horrible and the voices aren't the same. Matthew Brodrick will always be Simba. TLG exists just to make money off of it. But then again, 动画片 now in days are crap anyways. :P
