My name is hHiba.

In English, the first letter of names is capitalized :D And I just added a period at the end of the sentence since it was a complete thought.

Hi everyone, my name is hHiba im study law in three stage and i love my speciality. I'm in the third stage of my law studies, and I truly love my field.

I capitalized the first letter of your name. Usually, for levels or stages we use "in" so I changed it to "I'm in" and instead of "three" we would say "third."

When counting things such as this we use first, second, third, fourth, and so on. This is called "ordinal numbers." It's a little complicated, but I know you'll get it :P

Instead of "specialty" I changed it to field just for it to flow a little more naturally, but field can also work. So please don't worry too much :D Finally, just a few grammar changes were made.
