You don't need a 4-5 funds, since the SIP charges would take away some money (Rs. 33 / transaction in ICICI). Also, since you're a first time investor , tracking 4-5 funds might not be familiar for you.
I'd suggest 2 funds (both in Growth options since the time period is 5 years )
Large Cap : one of following (decreasing levels of recommendation as per me)
HDFC Top 200 (G)
DSP BR Top 100 (G)
Birla Sun Life Frontline Equity (G)
IDFC Imperial Equity (G)
Multi-cap: one fund
Reliance Regular Savings Equity (G)
Split the amount between the funds in 50:50 and happy investing !
