  2. How do I post 2 data?

Not sure what you want to do. Are the "decimal" numbers float data type? If you want to change floats so that you can put them into a string, use dtostrf().

char mystr[40];
float pi = 3.14;

void setup()
{
   Serial.begin(115200);
   char pistr[6];
   dtostrf(pi, 6, 2, pistr);
   sprintf(mystr, "The value of pi = %s", pistr);
   Serial.println(mystr);
}

void loop()
{

}

Have you looked up how a POST request is formed?

name1=value1&name2=value2

Try implement this with sprintf.
