Can I use fonts licensed with the UFL for making “things” (images, videos, documents etc.) – even for commercial usage –, and license them with other licenses (or keep the copyright)?
Yes you can. The UFL is pretty much the same as the OFL in these respects. From the Ubuntu Font License (boldface mine):
This licence allows the licensed fonts to be used, studied, modified and redistributed freely. The fonts, including any derivative works, can be bundled, embedded, and redistributed provided the terms of this licence are met. The fonts and derivatives, however, cannot be released under any other licence. The requirement for fonts to remain under this licence does not require any document created using the fonts or their derivatives to be published under this licence, as long as the primary purpose of the document is not to be a vehicle for the distribution of the fonts.
