38 C is on the top part of a normal body temperature, for some it would be a fever. It depends on the person.
A high fever for a 4-year-old is typically considered to be a temperature of 102 degrees Fahrenheit (38.9 degrees Celsius) or higher. It is important to monitor the child's fever and symptoms closely and seek medical attention if necessary.
9 year olds can survive up to 93 degrees celsius at 10% humidity like in a sauna but at 90% humidity the 9 year old would perish shortly after it reaches 47 degrees Celsius.
Most doctors - and the American Academy of Pediatrics (AAP) - agree that a normal body temperature for a healthy baby is between 97 and 100.4 degrees Fahrenheit (36 to 38 degrees Celsius). If your baby's rectal temperature is above this range, he/she has a fever. If your baby is less than 3 months old and has a temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher, call the doctor immediately. For a baby between 3 and 6 months old, call if his temperature reaches 101 degrees Fahrenheit (38.3 degrees Celsius) or higher. If your baby is 6 months or older, call if his fever reaches 103 degrees Fahrenheit (39.4 degrees Celsius) or higher.

37.5 degrees Celsius like any other human being
YES. That is a very very high fever. Especially if she is only seven. Call your pediatrician immediately.
A high temperature for an eight month old would be considered to be around 100.4 degrees Fahrenheit (38 degrees Celsius) or higher. It is important to consult with a healthcare provider if your baby has a fever to determine the appropriate course of action.
40 degrees Celsius is equivalent to ([9/5]*40+32) = 104 degrees Fahrenheit. 104
I'm guessing you actually mean 102.9 degrees Fahrenheit since 102.9 degrees Celsius would be 217.2 degrees Fahrenheit and no human can survive at that body temperature. If you meant 102.9 degrees Fahrenheit, yes, this is a fever for a 9-year-old and they should be taken to see their pediatrician to find out why they are having a fever. It's certainly possible that they have an infection and should be evaluated to make sure it's nothing serious.
110 degrees Fahrenheit is 43.3 degrees Celsius. Don't use the old word "centigrade".
37 degrees Celsius is considered a normal body temperature for humans. It is not old or hot, but rather a typical healthy temperature range.
37.5 degrees Celsius is 99.5 degrees Fahrenheit. Don't use the old word "centigrade".
