And off cource, my little humble channel has some bonsai content as well:

I'll give you some feedback on the pictures.

Jade just needs to chill and grow I think. Get used to the watering cycle, how much it grows given how much sun it gets, and let those leaves come out and develop. 

Jasmine looks like it was recently potted. I would just let it get used to it's container and make sure you can keep it healthy. Once you are sure it'll say alive and is growing, I would cut back a bunch of those dead (?) branches and maybe decide which leaders to keep and prune it, so the growth that it does put on will go to the right branches. Depending on how much of the roots it lost, you might have to trim it back a bit just to keep it alive.

Juniper L you might want to cut a branch or two but just keeping it alive and if it's growing strong, maybe putting it into rocky soil to help develop the roots.

Juniper S this guy's gonna grow really slowly unless you put it in a bigger pot or in the ground. I guess you could wire that main trunk but it's gotta grow a lot before you can do much with it.

Juniper C same as Juniper S.

Please post the pictures into the forum.
