[bsharath]

I have few hundred videos in Youtube and i have a new order to advertise a real estate company. Can i insert the 1 min AD into my video and still be able to Monetize them in Youtube?

You will only be able to monetize them if you have ads enabled on your current channel and are targeting the channel with the real estate ads. However, this is not a good strategy. Real Estate may not share the same user base and then your video ads will not have been beneficial.
