First is yarrow. Second may need to be seen in flower to tell which grass it is.

The feathery looking weed in the first photo is yarrow, Achillea millefolium. The second is one of common weed grasses - like crabgrass or quack grass - but would need to know where you are to single out the ID.

So after doing some research I've found out it's 100% quack grass. Any way I can kill this without going the round up route as weed b gone won't even make a dent in this stuff?

The second I think is a clumping fescue. I had the same thing in many places in my yard. This weekend I just completed tearing it all out and planting new. The previous Sunday I sprayed every area with round up to make sure it killed the plant down to the root. Then this weekend I dug up all the grass about 4 inches down and tore it all out. I then filled with topsoil and good dirt and planted new seed and toped that with peat moss to keep it moist and the birds away. Hopefully the new grass comes in and makes it though the summer. I am in ND so our summers are not as hot as other places so I think it will make it. Note this will come back every year if you do not kill it and dig it out.

Second also looks like clumping fescue to me.
