I know that data class are like simple models in kotlin with getters and setter by default and are as simple this:
data class User(val name: String, val age: Int)
是否可以为该数据类声明第二个构造函数？

you can set the data class like this
data class User(val name: String? = null, val id: String? = null, val email: String? = null)
你可以用多个构造函数来实例化这个对象
val userId = User(id = "123456")
val userMail = User(email= "email@email.com")
val userName = User("Name")
