No, a cactus can't survive without stomata. Each stoma is a breathing pore whose opening is controlled on both sides by guard cells. The pores are the points of gas exchange between the cactus and the outside world. For example, the pores release oxygen, for the purification of the environment; and take in carbon dioxide, for the plant's all important photosynthetic interaction with sunlight. So the stomata control what gets into and out of the plant's stem. The point therefore is to minimize inside water losses and maximize what's needed from the outside for making energizing photosynthetic products.
Water lilies will have less. Water plants have stomata on the sides exposed to air. Or if totally submerged, there are no stomata present. A cactus is covered with stomata but not as much as average plants.
yes but maybe
Many plants without conventional looking leaves (such as cactus) have evolved to have stomata (the pores through which carbon dioxide enters the plant) on their stems or on other surfaces. (Stomata are typically only found on the underside of leaves.)

Flowers help cactus plants survive in the desert by attracting pollinators. Because of pollination, the cactus plants may have fruits full of seeds. For example, the giant saguaro cactus [Carnegiea gigantea] depends upon bats for pollination of its huge, light colored bat blossoms.

A few. An infamous dessert plant is the cactus.
Plants without stomata include mosses, liverworts, hornworts, and algae. These plants lack true leaves and therefore do not have specialized structures like stomata for gas exchange.
A few examples of plants that do not have stomata are liverworts, hornworts, and some mosses. These plants have specialized structures that allow for gas exchange without traditional stomata.
Yes, there are plants such as the resurrection plant (Selaginella lepidophylla) and the ice plant (Delosperma sp.) that can survive very harsh conditions like extreme temperatures and lack of water without being a cactus. These plants have special adaptations that allow them to withstand such challenging environments.
Yes. The cacti may practice a delayed form of photosynthesis because they must close their stomata in the daytime but they, like all other plants, must take in carbon dioxide and release oxygen and water through those stomata.
