If my understanding of chemistry was as good as your command of the English language, I'd be able to tell you in exact terms what to do. Sadly, that is not the case.
I gather that you have dissolved aluminum, and it is combined with silver chloride?
That being the case, wash the silver chloride with hot water and more HCl. That should keep the aluminum in solution, and allow the silver chloride to settle well. You may find that the solution takes on a color that resembles finely divided silver chloride. In my experiences, that is nothing more than aluminum in solution. It won't settle quickly, but the silver chloride will. When the solids are settled, siphon the solution off, then rinse again with hot water. Repeat this process several times, until the rinse water is relatively clear.
Alternately, you can simply add aluminum in excess, along with some HCl (about 10%), and allow the aluminum to reduce the silver chloride to elemental silver. That requires that you stir the material frequently, so all of the silver chloride will contact the aluminum, which slowly dissolves in the process. When all of the silver chloride has been converted, the solids will be a gray color. Any remaining aluminum will continue to dissolve, and will give off bubbles, making it easy to recover the pieces. Remove them when you consider the silver chloride fully converted.
At that point, rinse the silver with tap water and allow it to settle. Siphon off the solution and repeat several times, until the solution nears being clear of color. At that point you can filter the silver to remove excess water. Attempting to filter before doing several rinses will be a very frustrating experience. The cloudy solution doesn't filter well, if at all.
