On the tab that shows the nameplate for the token, there should be a button with three vertical dots to the right of the word "General". Hovering over that button yields a dropdown menu with checkboxes for player permissions. If you check "See," your players should be able to see the nameplate for that token. (Hiding the player permissions checkboxes in this way was a change that was introduced in the last few months. I'm afraid I'm not a fan.) Edit: Here's an earlier post I replied to regarding the same issue; this one has screenshots: <a href="https://app.roll20.net/forum/post/9841744/show-npc-nameplate-to-players" rel="nofollow">https://app.roll20.net/forum/post/9841744/show-npc-nameplate-to-players</a>
