Timing marks and how to set timing on toyota corrolla 1994 canm belt snapped and need to replace

Both 7afe and 4afe (engines for 93-97 Corollas) are non-interference engines. It's highly unlikely there is any damage to the valves.

There is a very good chance that the valves are bent or worse, however the camshaft lines up using a pin inserted through a hole in the camshaft sprocket, looking at the camshaft sprocket the holes line up at 12 o'clock, the crankshaft is lined up using the indent on the crankshaft sprocket and an indent in the engine casing, you will see this indent at 2 o'clock, make sure the tensioner is free in movement and the spring is in good working order, undo the tensioner then pull it to the left then tighten up, fit belt then release the bolt so the tensioner can tension the belt, temporarily refit the crankshaft pulley then rotate engine a few times, check the timing marks again and check the belt tension, there should be a movement of 5 <>. 6 mm at the belts longest length, if not then repeat steps, if everything checks out then refit everything then try starting up the engine, as i have stated earlier there is a good chance damage has been done,
