Question

Is it possible to use Asset Sheets in Godot like in this Video?

Your means sprite editor? If yes, you can use animated sprite or atlas texture.

I found it already but I mean 2D Skeletons.

No, there is no specific skeleton 2d editor like animated sprite or atlas texture, but you can use bones I means you can create bones in the editor
