How to attack on RC4

Question

Friends, I am working on a project where I need to crack as much keys as possible for RC4 algorithm. I would request you to go through RC4 algorithm before reading his question.

I have given 50 different files (A00.data,A01.data...A49.data) each containing millions of lines. Every record of file contains 5 tuples

1. Initial Vector[0]
2. Initial Vector[1]
3. Initial Vector[2]
4. 1st byte of PRGA algorithm

Every key contains 8 bytes (3 bytes of Initial Vector-given + 5 bytes of secret key)

How can I apply any specific attack (ie RC4 ) and find the keys (5 secret bytes) from millions of rows in each file?
