There were "Beasts" in Revelations 12. Are they literal "beasts" or will they be Human persons?

They willl probably Humans who will exalt themselves other than God.

There are 2 beasts mentioned in Revelation.

1) the anti-christ (beast that comes from the abyss)

2) the false prophet (another beast from the earth)

Satan indwells the first beast (anti-christ) and gives him his power. The second beast makes the earth worship the first beast. Both these beasts are men.

They are both thrown into the lake of fire when Christ returns.

Satan is a fallen angel. The first and second beasts are men.

The Beast in Revelations refers to the Roman government.

The beasts are political entities or social organizations or systems.

Talking about Satan and the mark. And beast that will come up out of the sea. The Anti-Christ is the main beast it was referring to.

the beast represent humans...

Who knows, for all we know it could be talking about werecreatures taking over...

I wouldn't worry about it. Its a fable. And not even a particularly interesting one.
