Which languages most closer to the Turkish language

[placebo]

I think,

1- Gagauz (I understand 100%)
2- Azerbaijani (I understand 95-100%)
3- Crimean Tatar (From Kipchak group but I understand much better than Turkmen even sometimes better than Azerbaijani language, I understand 90-95%)

I doubt these are a different language.

To me;

1) Gagauz= 98%-100%
2) Azerbaijani= 90%-100%
3) Crimean Tatar= 70%-80%(this is the "literatural" one, the Kipchak version is less)
4) Uzbek= 60%-70% (the closest Central Asian Turkic language to Turkish, even more than Turkmen, I think)
5) Turkmen= 60%-70%
6) Uyghur= 50%-60%
7) Kazakh= 50%-55% (I also know some Kazakh)
8) Kyrgyz= 45%-50%
9) Nogay&Kumyk&Karachay-Balkar= 45%-50%
10) Tatar&Bashkir= 40%-50% (but Tatar slightly more)
11) Altay&Khakas= 15%-30%
12) Tuvan= 15%-25%
12) Yakut= 10%-20%
13) Chuvash= 0%-10%
