1) you will get string as the value of radio so it will be varchar type
2) for check boxes any one can have multiple values so you need to create a separate table(working_project) for this values( data type will be same as radio) and another table for mapping(user_working_project)
user_working_project table will containing user id and working project id
e.g one user has id=1, and working_project=1,2
then in your user_working_project table entries will be like this:
user_working_project_id working_project_id user_id
1 1 1
2 2 1
