I can’t help you on the first ones but here are the ones on the bottom.
“ El muchacho” would be the best choice because it is asking a question and “mañana, dia, and hola” all have a past tense sort if deal to them.
I think it’s voy....because voy means
“I’m going, I go, I arrive....etc”
So your sentence is...
Yo no voy llegar a las de la tarde.
Translation:
“I'm not going to arrive in the afternoon.”
Here you go :) I believe this is all correct
B is the future form for yo.
