Well it can be important to know which weeds you have so you know which are annuals and which are perennials. First one looks like grass! Second one is Bittercress, an annual (already setting seeds and dying in your picture) Third/fourth: yeah, a dandelion, a perennial with a taproot Fifth:looks like a type of grass Sixth: perhaps deadnettle - Lamium is the scientific name, I think it is an annual, already dying Seven: a grass of some type, perennial Eight, hard to see, but looks like seed heads on a grass Nine - not sure the name, but a weed! Ten - same as seven, I think Eleven - a weedy member of the Ranunclus family, I think Twelve - japanese honeysuckle, a weed and woody vine 13/14: looks like a Rubus family member (probably has tiny prickles) 15: more japanese honeysuckle (red stem and lobed leaves very characteristic) 16: a grass, probably not bad 17: not sure 18: wild garlic/onion; will die down in summer but then come back from little bulbs; multiplies over time to make bigger clumps 19: think that is a maple tree seedling with dandelions 20: a baby oak tree with some weedy geranium under it 21: geranium (weedy)- there are good geraniums, just not that one 22: more maple tree seedling 23: don't know that vine 24: a perennial weed, not sure of the name 25: can't really tell from the picture if that is a grass or what

Poa T (rough bluegrass) possibly?

no. not sure what that is. roughstalk bluegrass is notable for very thick seedhead stalks and not very dense. seedheads looks more robust on emergence but when it finally flowers, looks like regular bluegrass. that seedhead doesn't look like any of the poa types.

Some kind of millet but various species have escaped cultivation and bird feeders so not sure which it might be. I am leaning to foxtail millet.
