The first two could also be silver Polish but I would have expected to see a more defined crest. The middle one could be a mottled Houdan. The last is a white crested black Polish .
I believe I see two easter eggers, a barred rock, and two production reds. At this point, I'd guess the EEs and rock are pullets and the reds are cockerels.
What did you order? I would guess the white ones are white Rocks or Leghorns. The reds I would guess at production reds and/or red sex links. My first thought on the blacks was Australorps. I think you're right on the first bunch being BLRW, I think they have rose combs. It would help if...
It's a lot easier to tell what they are when the pics are of them standing naturally. How old are they? Does the first one have feathered legs? If so, partridge Cochin. If not, partridge Rock. The second one might be a dark Cornish but really need to see the comb and it standing naturally...
The first I would suggest is possibly a Faverolle/Polish cross roo. The second and third I agree are OEGB hens. The coloration on each is specifically hen coloration. Roos won't be colored like that.
Modern Games have single combs. The birds in the pictures had definite pea combs. They also don't have the tight, close feathering of the Modern Game. https://www.backyardchickens.com/products/aseel
The pics I saw on the link were of a tall, rangy, leggy, roo with loose feathers and a pea comb. Modern games tend to be more compact in type but still tall and leggy with tight feathers and a single comb.
So, looks like a single comb. Then my guess for her would be Welsummer.
The last one I'm still going to go with game cross. She isn't built quite right for an OEG and her legs are on the darker side.
Based on the coloration (dark, splotchy red over the wings and back) and the long pointy saddle feathers I believe I see next to the tail, I'm going with roo.
At this point, the coloration points to pullets. Possibly EEs but easier to tell with individual pics showing natural stance/carriage, leg color, and comb.
