That depends on how you are using the vectors. If a person moves from A to B and then from B to C, you can add two motion vectors AB and BC to get the total motion vector AC. But force doesn't work that way.I think this question doesn't makes any sense because vector algebra is applied for simooultaneous vectors(here force). I think direction doesn't matters but u can take both in same direction.
The magnitudes of the forces add like this only if the forces are acting in the same direction.Suppose if I applied a 4N force and then 2N force on an object , what will be total force. Note I didn't said simoultaneously, I mean one after the other, then what will be the total force , I think 6N
Of course the direction matters.I think direction doesn't matters but u can take both in same direction.

Also, "textspeak" such as "u" for "you" is not allowed at this site.

I don't think that makes sense. If you have some object that is moving along a path, and you apply a force to it, that force could cause the object to change direction (or not, all depending on the direction of the force and the direction the object is moving). If later a different force is applied, then that could cause a different resulting direction for the object. To the best of my knowledge, you don't add vectors that aren't acting simultaneously (simoultaneously is not a word).Can we add two vectors which are not acting simoultaneously by the vector law of addition.

Also, if the two forces are applied at different times (i.e., not simultaneously), how much time elapses between the times of the two forces? One second, one hour, one week, ten years?
You can if it makes sense for the context of the situation . For instance a displacement of 3km due north followed by a displacement of 4km due east. Those displacement vectors can be added to give the overall displacement.Can we add two vectors which are not acting simoultaneously by the vector law of addition.
