Haha nothing but sticks in the snow will be practically impossible to ID. It would be better if you provided some kind of size reference or mention how tall and wide. Right now, a yardstick stuck in the snow next to them would be one method. Common object could act as reference, too. Big trees — a good look at the bark is sometimes helpful.
Ones with some leaves and/or dead flowerhead clinging would benefit from a 2nd close up shot. Some of those are likely perennials or annuals and need to be cut to the ground and removed.
DEFINITELY NEED LOCATION — PART OF THE WORLD AT LEAST.
....the thorny little shrub in the very last photo looks like a barberry to me.
Learning never ends because we can share what we've learned. And in sharing our collective experiences, we gain deeper understanding of what we learned.
