Is it possible to ID this flock or some of them?

Smaller terns look like common/white fronted. Looking at eBird, seems more likely that they’re White-fronted Terns.

Crested Terns for sure. White-frinted Terns have a black bill for a start (at least in non-breeding plumage), they are never this numerous on the coast.

I was talking about the smaller terns amongst them. E.g in the first image on the far left, directly in front of a crested tern

There’s about 5/6 that I can see throughout the photos

Gotcha. Havcing copied photi and zoomed in, I can see a smaller tern in that photo but I would not like to call it.

I agree, photos aren’t good enough to call it on, but by process of elimination they’re either common or white fronted terns, and as I said, looking at eBird, white fronted would be more probable.
