I create objects at runtime. How i can count how many objects i create and delete them if i have too many objects in scene.
I assume you have some sort of main script.
Increment a counter every time you create/instantiate a new object and decrease it when you delete one.
How i can find the first object, which i create in scene. All object have identical names ragdollprefab(clone).
Store them in an array as you create them.
