Oh boy, it sounds like your timing belt skipped some teeth or snapped and needs to be reset and possibly a belt replacement. It either that or you may not have any transmission fluid, check your fluids. Transmission fluid

The knocking noise could be a rod, , you can easily check that by taking the valve cover off, but timing has got to be off, and you could have damaged a rocker arm. There are several possibilities and only one way to find out. Keep me posted

Check compression, that help you determine the internal damage
