For example this line: https://elixir.bootlin.com/linux/latest/source/arch/x86/boot/header.S#L297. I think b means binary number, o mean octal number, h means hex number. But what does f mean? In most languages it means floating number but doesn't seem to make sense here.

That's a reference to a local label. A label comprising just a single digit is called a local label. The expression 1f
refers to the next (forward) label named 1
whereas 1b
refers to the previous (backward) label named 1
.
