Again, I am not a lawyer, but is there any way Jones and other people banned by YouTube and Facebook go to federal courts and use NJ ruling as a precedent?
If a plaintiff alleges violation of both state and Federal law in a Federal case, then the Federal district court judge construes both state and Federal law.
The Alex Jones people can go to Federal court and include among their claims that the banning was illegal under both Federal and state law (California, most importantly), and the Federal court will construe state law as part of its analysis.
