2. sabe
number 3 maybe is “conocen”
-Hola Anthony, yo me llamo (write ur name)
-Mi número de teléfono es (write ur telephone number)
-Yo soy simpático (I guess hahaha)
-Sí soy muy cómico or No, yo no soy muy divertido (If you're not funny)
-Yo soy (Idk how tall r u)
It should be hablé since if it talking about someone else. If it were to be you, however, the sentence would be “Yo hablo con Juan.” Comprende?
