Use of big name apps in a commercial video projects
I'm no legal expert, certainly - so do take this 'advice' with a pinch of salt - and I'm not sure what you mean by commercial, but I'd probably err on the side of caution and, instead of replicating a Facebook post exactly, just do an approximation of it with motion graphics if you've got the time/budget.

To be honest, though, unless this is going out on TV, you're probably fine to use FB/Insta/Whateveragram provided that you're not suggesting that you're affiliated in any way and that those programs aren't the cause of crime/immoral action in the film.
