can one extend for another year on a multiple b visa in Thailand? or do they have to leave to make a new one, is there anyway one can extend another multiple b without leaving Thailand?

If you meet the conditions for an extension of stay you can do so on any entry during the last 30 days of the permitted to stay period. But if you are asking about obtaining a new multi entry non immigrant B visa that would not be possible inside Thailand. http://www.immigration.go.th/nov2004/en/ba...p?page=service#

i would like some help on the visa fee if anybody have knowledge of it.
