A HashMap is a variable, just like an int or a String. If you're storing your Views in a HashMap and want another extension to retrieve them, I think you have to compile the two extensions together, and do something like this.

ExtensionOne.java

public class ExtensionOne extends AndroidNonvisibleComponent {
    public HashMap<String, View> views = new HashMap<>();

    public ExtensionOne(ComponentContainer container){
        super(container.$form());
    }
}

ExtensionTwo.java

// You'll also have to import ExtensionOne

public class ExtensionTwo extends AndroidNonvisibleComponent {
    public ExtensionOne(ComponentContainer container){
        super(container.$form());
    }

    public View getView(String key, ExtensionOne extensionOne) {
        HashMap<String, View> viewsMap = extensionOne.views;
        return viewsMap.get(key);
    }
}

My code may contain errors as I didn't compile it.

You are already removing view from screen, so I assume you meant to destroy view after removing it.
Well, Android does that for you. Removing it from view hierarchy is enough to tell Android to destroy it when required.
