Q: Importing library from my computer to my iPhones library

Mac Mini OS 10.10.5

iTunes 12.3.1.23

iPhone 6s +

Hi  I am having trouble importing some of my songs and albums from my Mac Mini's iTune Playlist to my new iPhone's iTunes Playlist.

I think it may be that they are maxed out on their allowed device limit of 5 but I do not know how to check if that is the case. Can some one please let me know how to check if the songs limit is maxed out or if there could be another reason some of my songs are not importing correctly to my phone?

Also the iPhone's Playlist in iTunes on my Mac Mini shows the missing songs but they are greyed out and when I try to sync with my iPhone the playlist the whole Playlist does not sync.
