Blaze Release is only used by Sasuke, so it might be a combination of his Lightning Nature and Fire Nature to make it, similar to Yamato's Wood Nature made from a Water and Earth Nature.
Earth and Water Release
It never says what Karin's chakra nature is.
Asuma has a Wind Nature affinity. He also has a Fire Nature.
Nature chakra is the energy from the earth. Not elements. Naruto's element is wind, not fire. It would be very hard, or nigh impossible for Naruto to attain the ability to create a fire Rasengan.
Currently, Sakura does not have any chakra nature.

his chakra nature is wind but he can also use nature energy (if you count that as a chakra type) but other than that no
---Wind- We haven't been told this; but because Konohamaru used Rasengan (Rasengan is wind manipulaton) against one of Pain's body's, this tells us he's wind.--- I strongly disagree, based on facts that is... The truth is that we don't know what chakra nature Konohamaru has, and it may be that neither he nor Ebisu knows yet. Rasengan is based on chakra manipulation and it has nothing to do with element manipulation.Element manipulation CAN be added but it is not mandatory.Jiraya for example had fire and earth element chakra,yet he used rasengan.Naruto learned rasengan without knowing nothing about nature chakra, but when he mastered wind manipulation, then he created both Wind Release: Rasengan and Wind Release: Rasenshuriken.
Itachi has two chakra natures, them being Fire and Water.
Asuma has a Wind Nature affinity. He also has a Fire Nature.
Nature chakra is the energy from the earth. Not elements. Naruto's element is wind, not fire. It would be very hard, or nigh impossible for Naruto to attain the ability to create a fire Rasengan.

I belive that Tenten has an Earth Nature affintiy yet I'm not really sure.
