First there are the 5 villages
- leaf
- sand
- stone
- mist
- cloud
Then the hidden
- waterfall (kakuzu)
- steam (hidan)
- rain (pain and konan)
Dont forget hidden sound and grass. Then the uzumaki village and hidden frost village.
Also in the naruto manga (i forgot what book but the one with edo haku and and edo sasori) it says that the main hidden villages asked hidden frost and steam to move to a safer place so it was somewhat involving them. Then when sasuke revived orochimaru and they went to the battle field with karin jugo and suigetsu (and the past hokages) doesnt that count as hidden sound.
