Stick them in a prepared bed of loose soil up against your house or a garage or shed on the most wind protected spot you have facing preferably north or east. The less light the better. Tucked behind a shrub etc.

They've calloused well and now's a great time to do "dormant winter cuttings." You might keep one in your glass of water over the winter and move it to a pot and keep it in bright window when the roots start catching up to the size of your cuttings.

They'd prefer to be outside. Check on them mid-summer next year and they should be ready to move to a container or into their permanent planting place.

And mulch them.

The east side of the house is about 7ft wide, bordered on the north & east by a wooden fence & on the west by the house. In winter it's filtered or part shade, so that would be ideal, yes? & it's ok to plant now, even though there aren't any roots yet? They're about 3 foot long, & only have 2 or 3 leaves on the tips, is that ok? Sorry for all the questions, but I'm a novice gardener at best & this is my first attempt at planting trees.

Should be OK as long as proper soil moisture is maintained. Willows are very easy to grow from cuttings. I've seen a number of stories about where people stuck willow posts or sticks into the ground with no intention whatsoever of having them root, only to come back later and find their fence posts/stakes rooted and growing like crazy.
