By default, we can create validation rules using checkbox or dropdown list.
Can I create 2 new validation rules: Text box - to user insert new information and Date field - to user insert a new date as propertie of the ticket.
Which forms I need to change? Exist any customization about this?
I am not sure I understand what you are looking to do. Out of the box you can add a property with a text field for a user to fill in. You do not need a validation rule for that. Regarding the date property, currently we dont have a validation rule type that has a date selector. This would be something that would need to be an enhancement. I dont know of any way to do that even with a lot of customization i think it would be difficult due to the way that property values are stored in the database. I would recommend posting an "idea" for this here on the communities.
Thanks for your information.

Just add the property with no validation rule.
