I have a mesh like a picture below. How can I change the element size or remesh the model in Hypermesh? I know that I can do it one by one. But is there any way to do it faster concerning the current mesh geometry?
No, the mesh is not created in Hypermesh. It is the result of a simulation, which consists of the stress and strain state from the last simulation step.
I need also to have this information in the new mesh.
That is because you are using the wrong tool for the job.
Again, this is NOT much of a pre-processing matter. You need to look into the documentation of the solver you are using (Abaqus/ANSYS/DYNA/COMSOL/..) and find out how to map results from one mesh to another.
