A weed is a plant that is growing where you do not want it. Most of what you show are flowers. It depends on you if they are weeds. I do not recognize #5 but think it is used by butterflies.

It is always best if you save any flower seed packages so you will know what you planted. Rain or other things may move the seed/plant but you can do a search to find out how what you planted looks like.

If they are flowers then what are they called? I am just about positive that the first 2 pictures show a weed. It can grow on the lawn and when I try to kill it, it has the longest roots and can't be killed.

#3 appears to be wild violet. Some love it, some hate it. I have a neighbor who has a huge bed filled with it. I don't mind them, but usually pull them b/c they're never where I want them.

The first picture kind of looks like some Purslane starting to grow there, the second looks kind of like a Toad Lily and the third kind of like a Mallow. Whether what you have are "weeds" or not depends since as maifleur said a "weed" is a plant you do not want growing where you do not want it growing.
To help keep these potentially unwanted plants from growing more cover that bare soil with a good mulch. The reason many of these unwanted plants grow in bare soils is because Ma Nature does not want her soil left exposed to the ravages of the sun, wind, and rain.

Picture one looked to me like violas or campulia, toad lily, and marigolds. I was hoping the OP knew at least what the marigold was. Not to put the OP down but 30 minutes with a common gardening book showing pictures of flowers is time well worth it.

I have cleaned out the first year plants of several perinials when they did not have the foliage I expected. Most gardeners if the live long enough will do something similar.

Thank you to everyone who has tried to help me. I guess I did not explain the pictures well enough. I was wondering if they were weeds or some kind of flower. The picture that I am trying to show in 1 and 2 is of a perennial that grows in the lawn as well. I tried to center it and also put out 2 pictures to try to make it clearer. I have no idea where any of these came from. Most years I have planted bulbs and marigolds. This year I was too tired and only planted some dahlia bulbs and marigolds. I do have some perennials. The pictures that I have posted are all plants that I pull every year. The first and second picture are of a plant possibly a toad lily from the responses but it has a root that I cannot kill. It is so long and I would wonder why a toad lily would be growing in my garden and in the grass in the first place. I will try to let some of them grow longer to see what they do. Once again, thank you everyone for trying to help me figure out what they are.

Where is the location?
The bold foliage in the first photo could be Veratrum viride or another Veratrum. The foliage itself is quite nice, to me, and I would let it grow until flowering to have a positive ID.

As maifleur tried to tell you whether these are "weeds" or flowers depends on whether or not these are plants growing where you want them to grow or if they are plants you do not want growing where you do not want them. In one instance they are flowers while in the other they are "weeds".
I have rugosa roses growing in places that I do not want the to grow so those roses are "weeds", but I also have Goldenod growing near those spots and they are not "weeds" even though they have self seeded there.
