there is a very active fruit forum .. and the fruits there.. do things very differently.. as compared to general gardeners if you want to take them to the next level.. find those experts ... and they will surely have your pollination answers.. if anyone can actually ID a cultivar by leaf alone ... which i doubt ... maybe by flower.. but you will have to wait until next spring for that ... i am not very sure.. about the siting of these plants in your scape... black cherry trees can go on 60 to 80 feet... and apple 20 to 40 .. in the decades to come.. yours appear to be planted a foot or two from your foundation .. one would hope.. that the prior owner was bright enough to plant dwarf varieties... and surely you wont ID that from leaves alone ... but maybe the fruit pees can answer that by annual growth rates ... and do keep in mind.. that a dwarf of an 80 foot tree.. might be a mere 40 feet tall in not all that many years ... dwarf does not mean tiny ... good luck ken

forget about the lean.. improper planting ... if you want ideas on how to prune .... then we need a closer pic of the tree ... when young.. it could have been easily trained.. to a higher level.. i fear... that you might not be able to accomplish such.. though i cant focus deep enough into the picture to tell ... these things are a dime a dozen .... replaceable for around $20 or so .. here is your mind set ... enjoy it for a year or two [or less!!!].. learn about it.. hack on it.. try to get it into some preferable shape.. and if it doesnt work out.. GET RID OF IT .... and plant your own mistakes.. lol ... it was improperly planted.. improperly sited.. and most likely.. improperly cared for .. when i moved into my first home.. i spent 5 years trying to save every nightmare the prior owners left.. and then the day i got rid of the last one.. was the happiest day of my life at that house.. there is no reason to live with a problem... ken ps: and then you have a reason to get the cherry you want.. and plant it far enough form the driveway.. that it wont be a problem ... BTW ... there are flowering cherry that never have fruit.. and the fruit tree ... so if you want fruit.. i suggest you find the FRUIT forum.. and ask them.. which is best for your area ...

I agree with #1 thru #3 #4 looks like Populus balsamifera (Balsam Poplar) to me. #5 I agree, Tilia americana #6 Most likely Pyrus calleryana - Callery Pear, which is known to many erroneously as "Bradford Pear" because that's the oldest, best selling cultivar. Agree with #7 and #8 #9 Eleagnus umbellata - Autumn Olive #6 and #9 are aggressive exotic invasives which you should consider trying to eradicate, not transplanting. Also, I'd say it's tempting to transplant wild growing trees and shrubs and it can be done with care, but more often than not it ends in failure. Many wild established trees and shrubs, even when still young, resent the root disturbance and don't adjust well and end up dying or taking several years to recover. Some species are exceptions though and it doesn't always end that way, but like I said often times it does. Out of the trees and shrubs you listed, I'd think the smaller Blueberries have the best chance at being transplanted and would behave the best in the landscape.

I love wildflowers. I am still discovering blooms I have never seen before here at my place after nearly twenty years. I don't know any of the names but am always pleasantly surprised.
