there would be no sidewalk on which to walk
If there was no friction between the soles of your shoes and the sidewalk, you would be endlessly sliding down it until your momentum stopped you or you ran out of force.
If the forces oppose each other then nothing will happen, if the forces are acting in the same direction then they would actually be one force, equal to the sum of the two forces, if the forces are oblique then more advanced vectors would come into play... the ones that i know well enough to use but not teach.
The object remain stable in situ
NothingThe velocity remains the same
The question cannot be answered unless more specific information is provided about what the "four forces" are

Wehrmacht forces for the Ardennes Offensive happened in 1944.
Fear Effect happened in 1999.
Order of Merit of the Police Forces happened in 2000-10.
Force is a vector. So only depending on the direction of the forces we can give the resultant.
Without forces our atoms wouldn't be able to form and we wouldn't exist.
