You can use Check Boxes instead of Radio Buttons. Radio Buttons are useful when there should be only 1 selected item, and Check Boxes should be used when there can be multiple selected items.
As mentioned by proba1 radio-buttons are more suitable if you only want to restrict to one selection within a group, check-boxes will be more appropriate for your use case regarding multiple selections
