I can't give you a definite without seeing flowers/fruit, but pic one could be Australian Red Cedar (Toona ciliata) and pic two could be Tree Dahlia (Dahlia imperialis).

Hi There, picture 2 is Acer negundo (box alder) unsure of pic one, close up of leaves would help.

Pic 2 is Acer Negundo or Manitoba Maple, pic 1 looks like Tree-of-Heaven (Ailanthus canadensis)

Need a close up of leaves to be sure of # 1 - is a compound leaf, and need the whole leaf - probably 12-16 inches long.

If I am right about both trees, they will tolerate a lot of growing conditions, heavy pruning, and both thrive on neglect. They can tolerate pollution very well, and filter pollution very well.
Tree of heaven typically grows to about 70-90 feet, flowers around the mid to end of June, seeds are like the Ash samaras, branches are thick but brittle. In leaf looks like a substantial tree, after leaf fall, you'll wonder what happened to the crown. The wood smells a bit - the chinese call it the Stink tree. The wood can be sawn into lumber, and looks much like ash, except more yellow and more brittle. THe wood also turns well. Not bothered by many insects or diseases. Tends to grow as a single trunk with minimal branching.

Manitoba Maple is one of the "soft" maples, vs "hard" like sugar maple and black maple. It typically grows about 50-60 ft tall with a broad crown of 50-60 feet, or tall with little branching to about 80 feet. THe flowers are early in the spring - usually after Norway and Silver, and the keys are prolific and normally stay on the tree until fall. THe tree usually has a reasonably circular shape --free form-- until it is pruned. Pruning creates a rapid voracious regrowth in an attempt to regain what was lost. The tree does not compartmentalize very well, so centre rot becomes a problem. A bacterial infection often forms with decayed wood, turning the wood pinkish. The wood turns well, but can seldom be used for lumber because of the paucity of straight trunks and weak structure.

Both provide good shade and good wildlife habitat, but the seed fall does irritate many - both by the volume, and the number of seeds that germinate - often beside houses and on fence lines. Many people think of them as weed trees, but they will grow where many other species will not. Pick your location for the trees with care, and they can provide many years of shade and comfort.

And because they regenerate well, they provide lots of work for arborists.

Sorry Tree of Heaven is Ailanthus altissima. The other info is correct. And the male and female flowers can be on different trees, or on the same tree. Additionally, there are some people who are sensitive to the sap, and have an allergic response.

Hope you wanted a small forest of Alianthus!
