Each Temple has a maximum of 3 stars that they can acquire.
Every star you gain for each temple will provide you with a different percentage that increases the effect of that Guardians special skill.
To gain more stars for the Temples, you need to activate your Guardians several times.
You can see how many activations you need by clicking the yellow information icon next to the stars.
How do I level up the Temples of the Guardians?
