I created two forms. Import Campo dinamico

You can populate a drop down in form two using the gform_pre_render filter.

To get the values from the fields in form 1, you are going to have to loop through all the entries from that form, and extract the values from the specific fields you need. There are several ways to do this using built in Gravity Forms methods. Here is one:

[php]
// $all_leads will be an array of leads from one specific form
$all_leads = RGFormsModel::get_leads($form_id);

Then you would loop through all leads from form 1, and extract the values from the fields you're interested in, to populate the drop downs in form two.

The code I posted will go inside a function you create. That function will go in your theme's functions.php. The code I posted is not a complete solution but a pointer on how to get the values. You will need to write a function and get all your values with that line, then hook your function to the gform_pre_render filter. It will require a bit of PHP code to accomplish what you want to do.
