Hello Draksham !
Era's Medical College, Lucknow incorporates students on the basis of their marks secured in NEET.
Hence, you need to wait for the counselling procedure to begin in Uttar Pradesh under the State Quota form of application. Either way, you can apply through AIQ too, but you need to wait till the official documents regarding the Counselling procedure begins.
Meanwhile, keep an eye upon the following websites to keep yourself updated :

Year 3 : Rs. 16,60,000
Year 4 : Rs. 24,90,000
