How can I for ever stop Mac reopen apps when reboot.

There are up to three places you need to change to stop this behavior.

1. As mentioned, choose Shut Down or Restart from the top left Apple menu. It doesn't matter which one. Uncheck the box. You can then click Cancel. The OS will remember your choice under either menu item.

2. Open the System Preferences and click on the General tab. Put a check on Close windows when quitting an app.

3. In the System Preferences again (also mentioned above) under Users & Groups. Click on your user name and then the Login Items tab. Unlike what was mentioned above, do not blithely delete every entry. Remove entries that launch an actual app, not helper tools. Such as below, I would rather obviously create problems for myself by removing any of the launch items shown.

But some time when mac crash, automatically reboot or update OS

In a crash situation, when you get to the Login screen, hold down the Shift key to disable all login items. This will not get items that were open when you crashed that were not a login item, but it will help.

My question would be how often are you crashing? This should be something that is rare not so often that it is causing an issue.

The following article should help you here:

Automatically re-open windows, apps, and documents on your Mac - Apple Support

In particular, as well as unchecking the "Reopen windows when logging back in" option before shutting down or restarting, ensuring that no apps are enabled in the Login Items pane (System Preferences > Users & Groups) should also help you here.

To stop that annoying behaviour , simply close all the open apps (not only clicking on the red circle on top left of the window, but also quitting the app from the menu bar). Then, open the Apple menu, choose Shut Down, and uncheck the "Reopen windows when logging back in" checkbox. Click the blue "Shut Down" button. All done, when you will reboot (even after a crash) you will open your Mac without any open app.

When shutting down click the box so the app won't reopen,

also look in System Preference>User & Groups>

Login Items, any you find delete them.

But my Mac crash or Sleep failed ( laptop in black screen long time ).

Crashing can screw up many settings and/or damage files belonging to the OS or any other item on the drive.

Do as dialagbrian suggested and run EtreCheck. Copy/paste the output here.

If you close the applications, I don't mean just closing the window because the application. will remain open, then they should not open again after the next reboot.

I think you need to figure out why your Mac is crashing.

Please install and paste the results
