There's George Shelley.
He's my favorite, and he can play the guitar. He's the newest member of the band because it was Triple Jack(I believe) before he joined. Many say he is a mix of Harry and Louis. Tehe.
Then, there is Josh Cuthbert.
Isn't he just adorable? He's hilarious!!
There is also JJ Hamblett.
I couldn't find a gif of him, but he's just so hot, and he sings really well!
Lastly but not least, there is Jaymi Hensley.
He sings amazing, and he's really funny!
Union J is a beautiful band with four guys that have great singing voices. You can see for yourself.
I don't know much about them yet, but they seem really down to earth in some of their videos and are just adorable!
