Small question When shall I use "the other" and "another"?

A little doubt. What's wrong in this phrase? "The half of the born rabbits were guard for its mother and another ones were guard for its father."

Is it right? "Where are those foxes going with the chicken?" said the boy to his teacher while she was closing his eyes.

Is it usual these sentences on daily? "Where's Carl?" said John. "Out to the backyard." Replied his girlfriend. "Some of the flowers, after the hurricane, lost them amount for us." "I don't know why he was quite shy next to her." who were 21 and 18, respectively. (Another doubt in this sentence: Why the usage of the "to", is it correct?) "I don't get why your friend went to the home early." continued Monica, who was only fourteen. "Well," said his father, "most of this soccer players team are tired out whereas the another team is full energy."

When I have to use "how" and "as" I know that just "how" can make questions, but and in other cases like an explanation for instance.

When shall I use "your" and "yours" and what's the difference?

How can I acquire more vocabulary to do a letter? I already know that reading books I will prove in this topic. Could you tell me about another way?

When do use "ever" and "already" correctly? In my language, those two words have the same function. Examples: Did you ever seen one? Yes, I did. The night already began!
