Just iterate all the markers you have and use the following function to get the distance from the specific co-ordinate to the marker: computeDistanceBetween():

To compute this distance, call computeDistanceBetween(), passing it two LatLng objects.

I found it over here. Then just filter out all the markers that turn out to be close enough.
