Hello,

With the usual caveats:
Your last picture 89 is a Whiskered Tern. Please note:

• darkish grey rump and tail, concolourus=as dark as the back
• Shape of the bill, vaguely recalling a Gull billed Tern and not a White winged Tern
• Black ear covert spot and extensive spot on the nape merge together so you can imagine a bandana shaped band=a good head pattern for Whiskered Tern

And the first two look ok for "Eastern" Common Tern.
