The rest of the Jinchuriki use their Tailed-Beast chakra to transform into tailed beast but Naruto's tailed-beast mode is the result of his chakra mixing with Kurama, the yellow colour chakra is because of it. I'm not sure but I suppose it is because of the seal that is different from other villages so Naruto can't do partial transformation like B he couldn't do the Tailed Beast mode he tried but it resulted in miniature comic version, and now thanks to Kurama's cooperation, by combining Naruto's chakra with Kurama's chakra he was able to undergo Nine-Tails Chakra Mode transformation having yellow chakra cloak. I think the version 1 and 2 forms were because of small amount of chakra that was released from the tailed beast from the seal of Jinchuriki in the event if the Jinchuriki is threatened it's just like adrenaline rush only that more chakra is contributed by Tailed-Beast in version 2 and the beast can control the Jinchuriki's consciousness, and version 1 is also tailed beast chakra but Jinchuriki incorporates his own and modifies it another difference is 1 is beast like and 2 is humanoid. I think the Kurama mode is because of Kurama giving more of his own chakra and he stopped taking Naruto's chakra and he got this mode after the seal was released and he can transform into full scale replica of the Tailed beast, this mode is different than Nine-Tails Chakra Mode and is like opposite of version 2 the person can be healed if he is inside the constructs as opposed to version 2 causing harm upon touching the Jinchuriki. There is not much difference between Version 1 and Nine-Tails Chakra mode he uses many chakra arms in latter mode.

I don't suppose Kurama should manifest his physical form because his chakra shroud avatar is more capable of dealing with damage unlike other tailed beast. He has more advantage in that mode I think it's unique to Kurama.

Not sure if Mito and Kushina ever transformed into those forms because they are not shown in anime and manga and databook mostly tells stuff which is in manga. There was no possibility for their transformation because only Naruto was consumed more by hatred than Kushina after the attack of Nine tails on Konoha.
