I can't say I've heard someone use a name followed by girl, unless he was trying to just be cute? But without seeing it it's hard to guess what he might have meant. In conclusion don't worry about it, it's not normal lol

I think you should try having English lessons to improve your level. I'm a qualified teacher & native English speaker from London, I charge £10 p/hr if you're interested? you need to really surround yourself with English, music/movies/tv/other speakers. your post is understandable but there are some basic grammatical errors

Have you met my red balloon?

This world is very busy. I am surprised when I go far from my home, there's nobody who would like to know my name.
I didn't understood anything about the world the first time landed on this earth. Slowly, I began to understand things; when people say "Ocha" it means they talk to me or about me..that it belongs to me, that's my name. When people say "run" I know that it's walking very fast. I have been here long enough, it feels so weird sometimes that this world belongs to somebody.
Together with the family who raised me, we lived  upon a hill where there were only 15 houses. It's very peaceful and beautiful there.

Then one magical day, I saw a flying red ball in the air and it got stuck in a tree. I climbed the tree to investigate. As soon as I reached the thing it was attached to, the strong wind blew and almost made me fall and the red thing lifted me up higher and higher.. I have seen so many things from above, and sometimes I landed in a place <font style="background-color: rgb(255, 255, 0);">where the things took me.</font> (doesn't make sense)

There's a little boy or girl shouting when he sees my magical aeroplane.
"Balloon! Look!"
