To assign a collider on a prefab you need to do following steps:

Open the prefab and select the object you want to equip with a collider.

If you do not know, how you can create a prefab we recommend our tutorial creating prefabs.

Click on Add component.

Type into the displayed text box Collider.

There are two types of colliders.

3D colliders and 2D colliders

We recommend using 3D colliders.

Unity has different 3D colliders:

If Convex is selected the mesh collider is limited to 255 triangles.
