It's very easy to download the dramas from this website (no difficulty at all),
for my curiosity and query, I have tried to download one of episodes of the dramas, and I find out that
at least 7 Chrome-extensions add-on apps can be used to download this drama from this website.
Sorry for my frank saying that you have requested too many TV dramas here,
but actually you can download most of them by yourself as you can and wish easily.
Unless you requested TV drama which is very interesting and difficult to download from some websites,
and someone may help you, and you always just say " i don't know how to download ",
and no one will always do you favor to download all your requested dramas for you.
Hope you remember the tale about a boy who is always shouting 'wolves are coming' on the hill, ......
