ok ... on the groupshot the 4 to the right are in need of bigger pots they look totally rootbound to me (blades look droopy whilst the leafstems still stand upright) they also look a bit N heavy ... maybe its caused by the rootbound ... basically from the looks they could all use a transplant ... now these are auto and may react badly to a transplant
The dying leafs on the bottom is normal senescence (natural decay of oldest leafs it basically means the plant is using all the mobile elements before the leaf dies of) it can be postponed on other leafs by adding a bit N to the nutrients ... it usually happens to leafs that dont catch much light and it starts from the bottom up ...
C1 definately has thrips ... that silvery wrinkly damage track is typical thrip damage ... and since they are together they all probably will have already infected or soon will be
NY3 looks like damage the very young leafs sustained during the topping and it grew into holes as the leaf grew bigger
the rest i cant determin from that far away
and about the bugs the fungus gnats can be easely treated by putting a layer of fine sand 1/2-3/4 inch thick on the soil surface that prevents adults to burrow down to lay eggs and hatched adults to burrow out from the soil ... best do the same on the bottom of their new pots for the thrips you need Neem now that you still can ( before flower) and especially aim to bottom of leafs cause there is where the thrips live ...
about that assasin bug or whatever it is ill get back to you if i can correctly identify it ... i can tell its none of those you posted hehe
