How do we increase the size of font when using MetaSlider

We are using the free version of the MetaSlider plugin and have 3 sliding photos in rotation. The phrases associated with each photo are by default located on the lower left side of the photo, in one size and font.

How do we change the size, location and font of the phrase that goes with each photo on the Meta Slider?

Thank you in advance for your response, we have been trying to figure it out for a while now.
