app:layout_scrollFlags="scroll|enterAlways" doesn't works with LinearLayout

Question

I have start working on Android material design support library, and as a newbie I have some confusions. And, need your help. :)

1) Is it possible to use layout_scrollFlags="scroll|enterAlways" with LinearLayout?

2) I want a LinearLayout just below the Toolbar. I achieved it using AppBarLayout, but I want to scroll the LinearLayout not Toolbar on scrolling the content below LinearLayout. Using layout_scrollFlags="scroll|enterAlways" on LinearLayout doesn't works.

3) Can we use more than one AppBarLayout in CoordinatorLAyout and Toolbar in AppBarLayout?

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

    <LinearLayout

        android:orientation="vertical"

        app:layout_scrollFlags="scroll|enterAlways">

        <TextView

            android:text="TextView : 4" />

        <TextView

            android:layout_height="wrap_content"
            android:text="TextView : 5" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="TextView : 6" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="TextView : 7" />

    </LinearLayout>
</android.support.design.widget.AppBarLayout>

<android.support.v7.widget.RecyclerView
    android:id="@+id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

after implementing SaravInfern's solution, Here is what i achieved so far...

1.Scroll flags won't work on any container unless that component is designed to do so. Specific components like AppBarLayout are only designed like that.

2.do you want to hide the linearlayout after scrolling and show the toolbar??

3.As far as i know it is better to have only one appbarlayout, if you use multiple appbar layout, it may lead to scrolling problems

UPDATE 2 do like this

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="@dimen/app_bar_height"
    android:fitsSystemWindows="true"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/toolbar_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed>

   <RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:layout_collapseMode="pin"
    app:popupTheme="@style/AppTheme.PopupOverlay" />
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:padding="10dp"

            android:layout_below="@+id/toolbar"

                android:textColor="#FFFFFF" />
