I had these trees planted many years ago, but I don't remember which cultivars they are. I'd appreciate any help in figuring it out. My best guess for the red maple tree is Fireglow. (Sorry about the non-ideal zoomed out view.) As far as the small leaves, I have no clue
Good evening @Aces and welcome to the maples forum, I would like to say I can help, but there are just so many cultivars out there now, it is hard to ID from your photos. I don't think the large red is Fireglow. The lobesxare just not long enough IMO. Re the two yellow leaf photos, have a look at Katsura and Orange Dream. I can't see the leaf too well, but it might point you in the right direction. This forum might be of help with lots of photos of cultivars https://forums.botanicalgarden.ubc.ca/forums/acer-palmatum-cultivars-photos.208/ Sorry I can't help further at this time
I second what Acerholic wrote : It would actually be easier to make a guess when they're leafing out, in the spring. Meanwhile, have a look at the cultivars Acerholic mentioned, many photos taken at different times of the year, in different locations...
