second picture is elder, very good for berries and flowers. dont know the other ones sorry

The third is an ivy--which might need controlling but is good for the small blue butterfly and many other insects. Also the birds will appreciate the berries if we have a hard winter.

Need to see more of the first one, so can you post a pic standing further back, now we've got a close up of the leaves.

could the first be lilac ?

Thank you very much for your help, much appreciated.
