Dear Teachers,

1. Is it your first time abroad?
- This means : is it your first time you go abroad, right?

yeah

2. I'm a bit nervous.
- This means : I'm pretty/ quite/ kind of nervous, right?

This isn't quite correct. If you are pretty / quite / kind of nervous, you are more than a bit nervous.

3. Do you have a drink yet?
Have you called a drink yet?
- Which is more natural?

The phrases mean different things, cause if someone ordered (I'd use ordered or called for instead of called) a drink, he hasn't necessarily got it yet, as well as if someone has a drink, it doesn't necessarily mean he ordered it himself.

4. See you in a minute.
See you in a bit.
- Which is more natural?

The second one.

5) The school is located on/ in oxford street.
- Is this natural to say?

Thanks a lot.

You can use both, though, as far as I know, the British prefer "in the street".
