Yep, all three are Cedrus deodara. Fourth is certainly a Chrysosplenium, but maybe more likely the common UK native Chrysosplenium oppositifolium.
thanx guys!!! btw, yes it certainly is a Chrysosplenium, but I'm thinking more like C.alternifolium. The first photo of this plant I provided is a bit poor, so if you would like to take a look at this new one. You can notice the leaves aren't opposite? Am I correct?

OK, yep, that makes it C. alternifolium. Too right, I couldn't see clearly on the first pic, and C. oppositifolium is usually the commoner of the two.
