Hey,

Are there any possibilities of galvanic corrosion in between mating parts of Stainless steels & Duplex Stainless steels?

Unable to find any reference for the same.

Yes, it is possible. Austenitic stainless steels for example tend to be more electronegative than duplex stainless steel grades which could lead to galvanic corrosion in the right environment.

Likely the situation will be no worse than normal crevice corrosion in SS.
