Yes, although technically, strato-volcanoes *are* cinder cones (composite cones), built up of layers of ash. But the term "cinder cones" (ash cones) is usually applied to smaller cones that form within the vicinity of large volcanic calderas, such as Crater Lake in Oregon. They may be associated with either strato-volcanoes or shield volcanoes.
A volcano crater filled with water---CALDERA
The largest volcanic crater is Lake Tobi. This volcanic crater lake has an area of 1,130 km². It has a depth of up to 505 meters.
No, Crater Lake was formed by the collapse of a volcano known as Mount Mazama. Around 7,700 years ago, a massive eruption caused the volcano to collapse into itself, creating a caldera that eventually filled with water to form what is now Crater Lake.
There are over 25 recognized extinct volcanoes in the Cascade Range in the Pacific Northwest. Some examples include Black Butte, Mount Bachelor, and Mount Mazama (which collapsed to form Crater Lake).

Hells Canyon National Recreation Area is not within Crater Lake National Park. Indeed, that Canyon is not even administered by the National Parks Service; it's part of the National Forest Service. By road, the two are about 400 miles apart.

Crater lakes are usually round with (with a cliff round the edge) and sometimes deep. They all sit in the craters formed by the mouths of volcanoes.
