Investing Basics – Feel free to ask the most basic questions

Hello,
I have a single equity mutual fund in my portfolio (PPFAS Flexi cap). I’ve been trying to find another equity mutual fund (just for the mental satisfaction of not having all money in a single fund.)
Can you suggest one or at the most 2 equity mutual funds along with the reasons for selecting them.
In case you are unable to make suggestions on particular fund(s), it would be great if you can guide me to a resource that tells the most important factors to consider while choosing an equity mutual fund (preferably in the Indian context).

Thanks for your time!
