Can someone please tell me how to start multiple channels of  ADC? from zero using DMA? I am able to do it using the Polling method but I'm finding it difficult using the DMA

Go into the example selector and load the ADC_RegularConversion_DMA. That gets you the DMA part. It should be trivial to change that from 1 channel to multiple channels. There are other examples with more channels for other boards, you can use those as inspiration.
