I'm reposting snaps of the same birds as requested. The first two snaps are the original ones I had posted on the 15 Nov 2020. I've added 2 more snaps of the three birds together and the 5 snap of the bird in the middle. Hopefully, this helps.
To summarise so far, the general consensus seems to be, based on the very first image in post #1 at the top of the thread is from top to bottom of the image:
1. Steppe Eagle (no one has contested our original ID here)
2. Himalayan or White-rumped (but size perception remains a contention)
3. Long-billed (Indian) (likewise no one has contested our original ID)
EDIT: Ains has forwarded me the additional images which are below - Ains, I cropped one of them and lightened them slightly- I hope that is ok.
I don't profess to have much experience with these but the lightened, cropped image posted by Deb shows a juvenile Himalayan - the streaking on the underbody is now visible, as are the two white lines on the underwing-coverts (I imagine they mark the length of two bones but I don't know what they would be called). As Deb said, the head is made to look disproportionately small by the huge bulky body and broad wings.
By the way, I can't lay claim to the primary-counting technique - I think this was mentioned by Grahame in a post a couple of years back. Unfortunately the bird in Deb's linked image only seems to show 7, but they often show 8 as far as I can see.
- I agree, the primary counting is an absolute must when identifying raptors but as you say, this only works a/ in the absence of moult gaps and b/ where the primaries (often p10 or the innermost primary of the ‘projection’) are not swept back or out of position and thus ‘invisible’.
FFI - re: underwing. pattern features - I refer back to post #8 when I posted a quote from Forsman’s description of juvenile Himalayan - the short pale flashes are referred to as ‘patagium’ bars (Patagium is the triangular area of skin between the birds shoulder and wrist) - in this case the bars are on the lesser coverts and appear to follow the line of the humerus. The other larger and less distinct bar visible on the underwing is the median bar (pale line of median coverts).
