First one is teasel - a perennial that will self-seed if you let it. Good for bees, butterflies and birds.
Second one isn't very clear - might be an alder - but some clearer pics would help.
Third one is an elder (the sort you get elderflowers and elderberries for home made wine from - again, good for wildlife)
I think the fourth look like walnut tree leaves.
The fifth looks to me like a cupressus possibly Leylandii?
