The size of a cactus depends upon the type. For example, some cactus plants are naturally taller, such as the 40 foot/12 meter giant saguaro cactus [Carnegiea gigantea] and the 50 foot/15 meter old man cactus [Cephalocereus senilis]. And some cactus plants are naturally smaller, such as the 2 inch/5 centimeter living rock or fossil cactus [Ariocarpus fissuratus] and sea urchin or silver dollar cactus [Astrophytum asterias].
The size also depends upon environmental conditions. For example, cactus plants may not do as well outside their native habitat despite vigilant care. The normally towering old man cactus in the wild tends to grow no taller than 3 feet/90 centimeters in cultivation.
The size of cactus seeds depends upon the type of cactus. For example, the seeds may be succulent such as those of the mistletoe or wickerwork cactus [Rhipsalis spp], prickly pear cactus [Opuntia spp], or Echinopsis. Or they may be dry such as the woolly seedpods of the barrel cactus [Echinocactus].
The maguey is not a cactus but, rather, an agave. The size would depend upon the species and there are many.
How much of the cactus plant is water depends upon the size of the cactus and the amount of water in moving, processing and stored forms. But no matter the cactus' size and regardless of how much or little water that it holds, the cactus devotes over 90% of its inside body parts to handling, circulating and building up supplies of water.
They vary in size from species to species and my be the size of nails or like small hairs.

The redcap cactus, or Gymnocalycium mihanovichii, is a small, colorful cactus with bright red tops. It is commonly used in the horticultural trade for its ornamental value and is popular as a houseplant due to its small size and striking appearance. It requires well-draining soil and bright, indirect light to thrive.
Yes, the part of the cactus that's eaten dies. But no, what's left of the cactus plant doesn't die necessarily. It depends upon the size of the piece that's eaten, the manner in which the piece is removed, and the condition of the remaining body parts.
Cactus stems get bigger for two main reasons. One reason is normal growth. The other is an increase in the amounts of stored water, nutrient solutions, and energizing photosynthetic products. This last reason is why a cactus is ribbed. Its ribbing allows the cactus to decrease its size when it has lesser amounts in storage, and to increase with greater amounts.
