I found one good solution for it here. Below is the sample code -

<Window x:Class="WpfTutorialSamples.Styles.WindowWideStyleSample"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="WindowWideStyleSample" Height="200" Width="300">
<Window.Resources>
    <Style TargetType="TextBlock">
        <Setter Property="Foreground" Value="Gray" />
        <Setter Property="FontSize" Value="24" />
    </Style>
</Window.Resources>
<StackPanel Margin="10">
    <TextBlock>Header 1</TextBlock>
    <TextBlock>Header 2</TextBlock>
    <TextBlock Foreground="Blue">Header 3</TextBlock>
</StackPanel>

I hope this would help.

In the resources section for your main container put your style with a x:Key attribute and a target type of TextBlock. Then in each resources section for each StackPanel you can put a style where the BasedOn attribute is set to the key of your main style (don't forget to use StaticResource binding, not just the name of the key) and then say TargetType="{x:Type TextBlock}" and end the tag. this should bring the style into the StackPanel and style all of your TextBlocks.

<Window ...>
    <Window.Resources>
        <Style x:Key="tbstyle" TargetType="{x:Type TextBlock}">
            <!-- put setters here -->
        </Style>
    </Window.Resources>
    <StackPanel name="SPA">
        <StackPanel.Resources>
            <Style BasedOn="{StaticResource tbstyle}" TargetType="{x:Type TextBlock}" />
        </StackPanel.Resources>
        <TextBlock ... />
        <TextBlock ... />
        <TextBlock ... />
        <TextBlock ... />
        <TextBlock ... />
    </Stackpanel>
    <StackPanel name="SPB">
        <StackPanel.Resources>
            <Style BasedOn="{StaticResource tbstyle}" TargetType="{x:Type TextBlock}" />
        </StackPanel.Resources>
        <TextBlock ... />
        <TextBlock ... />
        <TextBlock ... />
        <TextBlock ... />
        <TextBlock ... />
    </StackPanel>
</Window>

<StackPanel>
    <StackPanel.Resources>
        <Style TargetType="TextBlock">
            <Setter Property="Margin"
                    Value="5" />
        </Style>
    </StackPanel.Resources>
    <TextBlock Text="Text" />
    <TextBlock Text="Text" />
    <TextBlock Text="Text" />
    <TextBlock Text="Text" />
</StackPanel>

You can accomplish this by overriding default text block style in the Resources of each stack panel:

<StackPanel>
    <StackPanel.Resources>
        <Style TargetType="{x:Type TextBlock}">
            <Setter Property="Background"
                    Value="Red"/>
        </Style>
    </StackPanel.Resources>

    <TextBlock .../>
    <TextBlock .../>
    <TextBlock .../>
    <TextBlock .../>
</StackPanel>

<StackPanel>
    <StackPanel.Resources>
        <Style TargetType="{x:Type TextBlock}">
            <Setter Property="Background"
                    Value="Green"/>
        </Style>                
    </StackPanel.Resources>

    <TextBlock .../>
    <TextBlock .../>
    <TextBlock .../>
    <TextBlock .../>
</StackPanel>
