Need IDs

[Maxx Yung]

Back from 1 week vacation, found these in my tank. No fish currently.
Need IDs for both the green thing and the white thing.

The 2nd last and last pic is focusing on that green animal near the waterline

Mostly copepods I see, the last 2 pics look like a flatworm.

Isopod munid and coperpods.

I know the white specks are copepods - so the 4th picture is isopod? And the 5th and 6th picture is a flatworm?

 

[Maxx Yung]

And are they harmful? If so, how to remove them? Thanks.

Yes, and the flatworm looks like a ghost flatworm to me.

No they are all good guys.

Picture looks whiteish, but it's green with brown circles inside.. you sure it is a ghost flatworm? It's not white as the picture seems to be.
