Make separate functioning droplists linked to the same data cells

I am trying to make a project status board. It is a table(spreadsheet) that has different stages listed on the top row. The rows below are for each project but some of the stages have multiple options. I would like to have a droplist under the stages with multiple options. The options are the same for each project. When I have more that one droplist liked to the same data cells when the list is used it changes the information in all the droplists

I have attached a file in progress for reference.

While I am at it, how can I get the droplists & check boxes to fit into the cells?

Thanks
