I encountered some license question about UEFN and Free Asset As Standard License

Hey guys, i hope this finds u guys well.

I found 2 problems for my project. First one is can UEFN Reference only in FAB use in Unreal Engine and commercially. Second one is can I use free asset from FAB as standard license commercially? Commercially here means I publish the game on steam and sell it.

Thank you in advance,
Dan
