OK, let's have a go. 4 is quite the stretch, but all the other match perfectly (at least in my head).
First the common:
Common(1,2,3,4)+FB
The common is Mark Wahlberg,
add FaceBook to that and we get Mark Zuckerbergand the answer is Marky Mark and the Funky Bunch (a hip-hop group led my Mark Wahlberg).
Now the clues:
<h1>hit</h1>
This will make "hit" big. It will even make it "the biggest", so The Biggest Hit (1998)
P227, M4
The name of 2 guns, so 2 Guns (2013)
iddqd
A cheat code that will make you invincible in doom, so Invincible (2006)
A Konami hit performs music
Now this one will be a stretch... Konami, had this game Guitar Freaks. Later Guitar Heroes popped up. In Guitar Heroes there was this character, who is named Izzy, which is the nickname of the titular character of Rock Star (2011)Thanks to Cerberus's answeranswer, this should actually be Contraband (2012), derived from Contra - a Konami game (part of Konami Classics Series: Arcade Hits), and band.
