guys please someone correct this mail for me please guys its an emergency

The part that starts with "I want to ask you..." makes no sense in English.

In fact, the first 11 words in this sentence should be thrown out. regardless of what you're trying to ask.
That is, don't ask an interviewer (or really anyone, but an interviewer in particular as they are often short on time) if you can ask a question. You can always ask an interviewer a question. That's a fundamental part of the interview process.

I am guessing you want to know 2 things:
1) What sort of interview it will be and
2) What you can bring or use during the interview.

So, instead write:

What type of interview will it be? Are there any limits on what I can bring or use during it?

The rest of the letter is fine, except you need to capitalize Thank in the last line and end that sentence with a period.

Best of luck to you!

Besides the above, you have a lot of unnecessary words.

Dear Mr ....

Thank you for studying my candidacy file. I will be ready for the interview starting Tuesday at your convenience. Please let me know if there are any restrictions on what I can bring into the interview.

Sincerely Aymanemsi4
