What actually are the six kalimas. I have seen people teach those to their children only in South Asian countries and say that memorizing these is necessary and only after learning and believing these you are a Muslim. Is it so?

I would like to know the system of Tahlil. In our country, we are taught to say ” La ilaha illallah ” 1,25,000 times, in which have to say once ” La ilaha illallahu Muhammadur rasul Allah” after every 100 time. If I say only ” La ilaha illallah” countless, would it be a complete Tahlil ? Please let me know the system of Tahlil in details.
