Hii Anjana Sharma
Try Below Test Class 
@isTest
public class MyApexFirstClassTest {
@isTest
    public Static void UnitTest(){
       	MyApexFirstClass.myFirstMethod();
        MyApexFirstClass.mySecondMethod();
        MyApexFirstClass.myThirdMethod();
        MyApexFirstClass.myFourthMethod();
        MyApexFirstClass.myFivthMethod();
    }
}

As you are performing static operations withing these methods, you can create a new Test class and just class these methods directly from the test class.

@isTest
public class MyApexFirstClassTest {
   @isTest static void methodName() {
      MyApexFirstClass.myFirstMethod();
      MyApexFirstClass.mySecondMethod();
      MyApexFirstClass.myThirdMethod();
      MyApexFirstClass.myFourthMethod();
      MyApexFirstClass.myFivthMethod();
   }
}

This should get the coverage for your class.

        test.startTest();
        MyApexFirstClass.myFivthMethod();
        MyApexFirstClass.myFirstMethod();
        MyApexFirstClass.myFourthMethod();
        MyApexFirstClass.mySecondMethod();
        MyApexFirstClass.myThirdMethod();
        test.stopTest();
