I'd get rid of the sycamore - it'll soon shade everything else out and stop you growing anything near it and it'll seed everywhere and you'll be living in a forest!
It's not as if you're short of trees, and even if you were, there are hundreds of trees I'd plant before choosing a sycamore
I'd see how the fruit tree (probably an apple) does this year before deciding what to do with it - it may need a bit of pruning but I can't really see the shape from the photo.
As for the mistletoe apple - it sounds as if it's happy the way it is
