Can someone tell me the difference

Hello Everyone!

On the list of films to ask for from San Juan de los Lagos there are different choices for marriage.
I just wonder what is the difference between them. Does one have more info then another?
These are the choices:

Informacion matrimonial
Dispensas matrimoniales
Diligencias matrimoniales
Exortos matrimoniales
Matrimonios

I don't want to loose out on any info if each of these contain different information. Which is better?

Thanks!

Sofia
