if the tank is about 6 feet then no problems for the silver shark as they need this space and needs to be in a group not singular. also the corys will be better in a group of 6+ and the betta will not be happy in a tank with all these other fish as they prefer to be a lone fish so i would recommend rehoming him.
silver dollars get very big too and need alot of room and again need to be in groups.
