No, those are Goldens sisters. They have also been cut from the show.

They kinda look like them tbh,

I though they were Feather's sisters, Sister 1 and Sister 2

They are Golden's sisters.

Where farleap and silentstalk going to be in the show before they removed some characters?

Yeah, but they're also Feather's sisters, right? Wasn't Golden Feather's older brother?

I don't know sorry...

Yes, Farleap and Silentstalk were originally in the book, under different names like many other characters, and they were always planned to be in the show. You are correct when they are Feather's sister in THIS version, as Golden was his older brother, but they aren't the sisters we see now.
