Hey balivalli,
I'm assuming your referring to the brush stroke effects.
As has been stated these are Photoshop brushes. The brush set use for the first image can be downloaded here:

Here are a few tutorials on how to load or install Photoshop brushes:

When you have created the appropriate background, create a new layer and name it
Brushstroke.
Select your
Brush Tool. Select the "brushstoke" brush of your choice from brush presets.
Use the left ([) and right (]) bracket keys on your keyboard to adjust the size of the brush up or down.
You can adjust the tool settings in the
Tool Options toolbar. I just used MODE: Normal OPACITY: 100% FLOW: 100%.
Set your foreground color to the color you would like your brushstroke to appear.
On the new layer you named
Brushstroke, position the brush outline to where you want the brushstroke to appear and click once.
(This is not exactly what was used in your example, but it will work)
In your layers panel, double click the
Brushstroke layer. This opens your layer styles. Add a
Gradient Overlay to the brushstroke.
Adjust the gradient to your liking and hit OK.
Select your
Horizontal Type Tool. Select the font you would like to use. Select the color of the font you would like to use.
The
Type Tool will create it's own layer. Type in whatever you would like to say.
Double click the newly created text layer to open a layer style.
Choose
Bevel & Emboss, adjust to your liking.
Chose
Gradient Overlay, adjust to your liking.
Click OK when done.
Select your
Horizontal Type Tool again. Select the font you would like to use. Select the color of the font you would like to use.
Type in whatever you would like to say.
You can add a layer style to this new text layer if you wish.
This is basically how it's done.
