use the fillViewport tag in your scroll

android:fillViewport="true"

Your structure will look like this:

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fillViewport="true" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:weightSum="1">

        <!-- codigo -->


    </LinearLayout>
</ScrollView>

If I understood correctly, you want the ListView that is outlined in red in your question, be an infinite ScrollView until the last post, and the top 2 images are locked.

If so, try the following:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.ajuda.ajuda.MainActivity">

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/relativeLayout">

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:src="@drawable/x">

        </ImageView>

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:src="@drawable/c"
            android:layout_below="@+id/imageView"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true">

        </ImageView>
    </RelativeLayout>

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

    </RelativeLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentEnd="true"
        android:layout_alignParentRight="true"
        android:layout_below="@+id/relativeLayout">

        <ListView
            android:id="@+id/lista_jornais"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_alignParentBottom="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            tools:listitem="@android:layout/simple_list_item_1"
            android:layout_alignParentTop="true" />

        <ScrollView
            android:id="@+id/scrollView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true" />
    </RelativeLayout>

</RelativeLayout>

The result was this:

You forgot to close the tag of your ScrollView. He can only have one child.

Put this line at the end of your code:

<ScrollView/>
