I just realized that the 2 pics are different species.

I also noticed that the leaves in the 2nd pic look like the leaves on my neighbors tree

If I were you I would just read up on the "Triangle Approach" to weed control on this site. I bet if you use a herbicide that falls under "level 2", this weed will be a goner.

Here's a link to the article

Ha, if you only just now realized those two weeds are different species, you do indeed need help with ID.

The first one is wild violet, a perennial, herbaceous plant. That appears to be an established colony that has been there for some number of years. It laughs at 2,4-D three-way herbicides.

The second one is a tree seedling, possibly maple. Mowing alone should rid you of those, but feel free to hand pull. Trees aren't big fans of being mowed, so spraying their seedlings in the lawn is usually unnecessary.

For chemical control, both of those are best addressed with triclopyr, which you'll read about in the "Triangle Approach" article that CPascal pointed you to.

I get a lot of those little maple leaves in the spring. I try to mulch the samaras in the fall, but I never get them all. Still have a handful some popping up here and there. I pull some, but mowing takes them out fine.
