Please help with spanish questions! Please and thank you

-Hace 3 horas que Ricardo espera. OR: Hace 3 horas que Ricardo está esperando.

-Hace 2 meses que visitaron a su abuela por última vez.

-Yo veía la televisión todos los días "cuando era chico".OR: Sí, yo veía la televisión todos los días "cuando era chico".

"cuando era chico" is optional, it´s just an aclaration, but it´s not really necessary (The affirmative answer in Spanish can be in a lot of different ways, mostly depending how you are seeing it, but these two forms are the ones they usually teach).

-Yo hablé con María. OR: Yo he hablado con María. (First one more casual, second one, more formal)

-Sí, yo hablé con María. OR: Sí, yo he hablado con María. (First one more casual, second one, more formal)

The word "Sí" (Yes) is used a lot to respond answers and the other sentences without that word are like you are telling that to someone just following a conversation or randomly, so I would use one the ones with the "Sí"

PD: I¨m from Argentina. (Spanish it´s my first language)
