Looks that you have a lot of troubles with arrays, the code you show have a lot of inconsistencies, for next time try to provide a Minimal, Complete, and Verifiable example in order to get better help. Here you can see the guidelines to create one: https://stackoverflow.com/help/mcve.

Also I suggest you to study arrays and variables in java.

I modified your code to run in this way, (it may differ from yours because I don't know everything you are doing).

Here is your modified code:

import java.io.IOException;
import java.util.Scanner;

public class Example {

    public static void main(String[] args) throws IOException {

        Scanner scan = new Scanner(System.in);
        int many = 10;

        /**
         * I fix this variables and initialize them to run your program
         */
        DataPenumpangPesawat name[] = new DataPenumpangPesawat[many];
        DataPenumpangPesawat address[] = new DataPenumpangPesawat[many];
        DataPenumpangPesawat sex[] = new DataPenumpangPesawat[many];
        DataPenumpangPesawat[] Gender = new DataPenumpangPesawat[many]; // This variable is never used
        DataPenumpangPesawat ktp[];
        ktp = new DataPenumpangPesawat[many];

        System.out.print("Input Data Many Passenger =");
        int lot = scan.nextInt();

        // Array Request User Data Input Entering Aircraft
        for (int i = 0; i < lot; i++) {
            System.out.print("\n Data to-" + (i + 1) + "\n");
            scan.nextLine();
            System.out.print("Passenger Name =");
            // I have a problem in here
            name[i] = new DataPenumpangPesawat();
            String name2 = scan.nextLine();
            name[i].setNama(name2);
            System.out.print("Address =");
            address[i] = new DataPenumpangPesawat();
            String Address = scan.nextLine();
            address[i].setAlamat(Address);
            System.out.print("Gender (1 = Male / 2 = Female) =");
            sex[i] = new DataPenumpangPesawat();
            // scan.nextInt gender = int ();
            // sex[i].setJenKel (gender);
            System.out.print("NIK KTP (NPM) =");
            ktp[i] = new DataPenumpangPesawat();
            int KTPP = scan.nextInt();
            ktp[i].setNik(KTPP);

        }

        for (int i = 0; i < lot; i++) {
            System.out.print("\n \n +++ +++ TICKET PRINT \n");
            System.out.print("Print Tickets to-" + (i + 1) + "\n");
            System.out.print("================= \n");
            /**
             * I initialize this variables with 1 because I don't know where they comes! You must change the initialization for real values
             */
            int pil2 = 1;
            int pil3 = 1;
            int pil4 = 1;
            int piljam = 1;

                }

                if (pil3 == 1) {
                    System.out.print("Class = Executive \n");
                } else {
                    System.out.print("Class = Economy \n");
                }
                // Print Destination City Passenger
                System.out.print("City of Interest = Yogyakarta \n");
            } else if (pil4 == 2) {
                System.out.print("City of Interest = Lombok \n");
            } else {
                System.out.print("City of Interest = Jayapura \n");
            }
            // Print Departure Date
            // System.out.print ( "Jam Departure =" + date + "-" + Moon + "-" + year + "\ n"); I commented this line because I don't know where the
            // variables date and year are.
            System.out.print("Jam Departure = \n");

            // Print Jam and Jam Arrive Departures
            if (piljam == 1) {
                System.out.print("Jam Departure = 09:30 AM \n");
                System.out.print("Clock Arrive = 10:40 AM \n");
            } else if (piljam == 2) {
                System.out.print("Jam Departure = 11:50 AM \n");
                System.out.print("Clock Arrive = 13:20 AM \n");
            } else {
                System.out.print("Jam Departure = 3:15 PM \n");
                System.out.print("Clock Arrive = 5:40 PM \n");
            }
            // Print Personal Data Passengers
            String nama1 = name[i].getNama();
            System.out.println("Name =" + nama1);
            String address1 = address[i].getAlamat();
            System.out.println("Address =" + address1);
            int gender1 = sex[i].getJenKel();
            System.out.println("Gender =" + address1);
            System.out.print("NIK =" + ktp[i] + "\n");
        }
    }
}

And this class:

public class DataPenumpangPesawat {

    private String nama;
    private String alamat;
    private int kTPP;
    private int jenKel;
    private int nik;

    public int getNik() {
        return nik;
    }

    public void setNik(int nik) {
        this.nik = nik;
    }

    public String getNama() {
        return nama;
    }

    public void setNama(String nama) {
        this.nama = nama;
    }

    public String getAlamat() {
        return alamat;
    }

    public void setAlamat(String alamat) {
        this.alamat = alamat;
    }

    public int getkTPP() {
        return kTPP;
    }

    public void setkTPP(int kTPP) {
        this.kTPP = kTPP;
    }

    public int getJenKel() {
        return jenKel;
    }

    public void setJenKel(int jenKel) {
        this.jenKel = jenKel;
    }

}

The output is:
