Legality of legal advice given by law student

any one can give legal advice if it will useful to others. no hurdle on it

The line between "legal advice" and "legal information" is often blurred. As a general matter, only a lawyer may give actual legal advice, whereas any non-lawyer may recite legal information. Furthermore, it is generally illegal for a non-lawyer or unlicensed attorney to offer legal advice or otherwise represent someone other than himself or herself in a court of law.

Hello, Greetings of the day!
For the query you posted, I would suggest that:
Yes, any law student can give legal advice but it should be useful to others as well as given with proper knowledge. 
For safety or to avoid any legal proceedings in the future, a law student can mention that it’s their suggestion and for further guidance, they can consult a lawyer while offering advice. With this, liability may shift to the seeker because they would have choice to whether take or avoid that legal advice given by law students.
Hope it helps
