If I bought a mutual fund long ago and bought some more today, and
then I sell an amount equal to the amount bought long ago, Will I be
charged the redemption fee? Does anybody know where I can find out
about the redemption fee of vatious funds or any information on
redemption fees in general?

Details on fees vary a lot from fund to fund.  I doubt that anyone can
give you a general answer.  If you have a specific fund in mind,
information about fees should be available for that fund.

May this site could help you out, it has helped me out a lot with
stocks, funds, and investing.
