Hello,
Yes, you can. There is no certain minimum age to appear for JEE exams. However for general category the age limit is 25 and for SC, ST etc. They have a relaxation of 5 years. For complete eligibility details, you may refer:

Why not, apart from getting admission in IITs, your success story will be published in top newspapers also. It's really good that a 16 year old student is clearing JEE advance. Also, you will be an engineer at the age of 20. It is really great, if you make it. Work hard. Nothing is impossible. Best of luck.

According to the eligibility criteria, if your score is good, then you can get IIT.

For this, you have to score good in your Diploma more than 85 percent in your degree.

You can give JEE Mains exam, by scoring good ranks in it, you may get IIT or NIT.

Hello Ajay,
As you have qualified to write JEE Advanced you can give it a try. It is not that only if you have a good coaching you should apply. You can self prepare and most importantly, if you are strong in basics, you can perform better. If you don't get a seat at IITs, then it is not an issue as you have got some good experience. And what if you clear the exam and get into an ITT? Be confident and give it a shot.
All the best!
