Puedo limitar de alguna forma para que mi encuestado solo conteste 5 posibles respuestas y después deshabilite el campo

Hi clinicardiopabon.sistemas,

Thanks for reaching out to Jotform Support. Our Portuguese Support agents are busy helping other Jotform users right now, so I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Portuguese, let us know and we can have them do that. But, it might take a while until they're available again.

Now, coming back to your question, if you want to limit the number of items that a user can select in the Multiple Choice field, let me show you how to do it:

1. Click on the Gear icon next to the Multiple Choice field.
2. Go to the Surveying tab.
3. Toggle on the Entry Limits.
4. Set the maximum to 5.

Give it a try and let us know if you need any other help.
