Answer 1

You input variable number only once. If it is 0 your program will end otherwise it will loop forever.

Answer 2

Like this it works, please look at the comments for what i changed:

import java.util.Scanner;

public class Main {
public static int numero ; // added global var numero
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
// removed input

//tu código va aquí
// removed if statement
do {
numero = scanner.nextInt(); // removed int
if (numero == 1){
System.out.println("Language selection");
} if (numero == 2){
System.out.println("Customer support");
} if (numero == 3){
System.out.println("Check the balance");
} if (numero == 4){
System.out.println("Check the loan balance");
} if (numero == 0){
System.out.println("Exit");
}
} while (numero != 0); // changed number to nunero

}
}

Answer 3

The input at sololearn is odd, you have to give all your input on separate lines before you push submit:
