Growing a Weeping Willow from Cuttings?

I received some weeping willow twigs in the mail. I've already planted them in a small pot. They're about a foot long. They are "not" branches. They are much smaller and thinner than a branch. I've had them for about 2 weeks and the willow buds are starting to sprout leaves. I've noticed that they grow more and more each day. And they seem to grow faster if I water them faster.

My question is, now that they're starting to sprout, will they grow together as one tree? Or will each sprouting twig become its own tree? Also, is it possible to take the willow twigs and entwine them together so when the weeping willow tree grows, the trunk will be braided?

I've tried looking all over online, and I can't find a legitimate answer. The only related searches are about pruning, watering, etc. I know all of this, I just want to know if each twig will be an individual tree.

Thank you so much for your help ((:
