Water once a week - twice in very dry spells, but give them a good soaking - a bucket full per half metre. They need the chance to dry out between waterings as roots need oxygen as well as water.
All evergreens lose leaves - they just do it throughout the year rather than in autumn. Yours look pretty healthy to me - they might be suffering a bit of transplant shock and you might need to replace one or two in the autumn/winter if they don't recover by then - but I think that's pretty good going so don't panic.
And yes, as Lyn says, prune off the top six inches to encourage them to grow thicker and more bushy - and don't spray them - they don't need it and we all need the insects
