Answer:
blank 1: tengo (meaning I have)
blank 2: asking when Juan's birthday is. If there is other information about when his bday is, then phrase it like this: Mi cumpleaños es el (insert day here) de (insert month here). So it would look like this with a random date: Mi cumpleaños es el doce de abril. (translation: my birthday is April 12) Remember that you don't capitalize months in spanish.
Blank 3: Juan could respond multiple ways here. He could say:
Hasta luego (what Maria said, meaning see you later)
igualmente (meaning and you, or you as well)
adios (meaning goodbye)
Explanation:
Hope this helped. Good luck!
