Hi Ju
A "counter" doesn't need to be fixed to a wall - see:
counter - definition of counter by the Free Online Dictionary, Thesaurus and Encyclopedia.
"counter
n
1. a horizontal surface, as in a shop or bank, over which business is transacted
2. (in some cafeterias) a long table on which food is served to customers"
As noted in the above definitions, "
counter" tends to be used in a commercial context.
Similarly, although you can have a worktop over floor-level cupboards, mounted against a wall. you can also have a unit in the centre of a kitchen. i.e. not attached to a wall, that could include cupboards, a sink and a
worktop for preparing food. "Worktop" could be used in either a commercial or domestic context. See:
worktop - definition of worktop by the Free Online Dictionary, Thesaurus and Encyclopedia.
"worktop
n (Cookery) a surface in a kitchen, often of heat-resistant laminated plastic, that is used for food preparation"
The term "desk" is used, primarily, for reading and/or writing, but can also be used in other contexts. See:
desk - definition of desk by the Free Online Dictionary, Thesaurus and Encyclopedia.
"desk
n.
1. A piece of furniture typically having a flat or sloping top for writing and often drawers or compartments.
2. A table, counter, or booth at which specified services or functions are performed: an information desk; a reception desk.
3. A department of a large organization in charge of a specified operation: a newspaper's city desk."
For "workstation" see:
workstation - definition of workstation by the Free Online Dictionary, Thesaurus and Encyclopedia.
"workstation n.
1. An area, as in an office, outfitted with equipment and furnishings for one worker and usually including a computer.
2. A sophisticated standalone computer used for a specific purpose, such as imaging."

PS I thoroughly recommend the Free Dictionary, quoted above, as it authoritatively answers such questions, both in an AME and UKE context.
PPS "There are
fixed sort of 'counter, worktop and desk'
against the wall for ones doing works for convenience where there is
no chair to fix with. So the users have to
stand and do their work. What shall I call this kind of working station?"
I'd probably call it a "work surface" see:
work surface - definition of work surface by the Free Online Dictionary, Thesaurus and Encyclopedia.
" - a horizontal surface for supporting objects used in working"
