First lot looks like Princess Sterling as she was sold with Fluttershy. In that lot I also see Princess Gold Lily with Pinkie Pie. I remember buying these new when on a bus trip, & only wanting the two princesses. Waiting for the bus I saw a little girl & her mother & gave the Ponies I didn't want to the girl so they went to a better home than mine (where honestly they would have just been spares). The other two princess & pony sets there look legit as well, featuring characters we know & love.
I've trusted Aliexpress with sending me Silverstream (prices for her elsewhere are sky high when she shows at all), & she too comes the way she was originally packaged.
Not as familiar with the second lot though, so will let somebody else judge that
