The distinguishing feature of a long-legged insect that makes it resemble a spider is its segmented body and eight legs, similar to a spider's physical characteristics.
Of course not, but there are 5 TOED chickens and possibly 6.
Time, and careful selection of which animals that are allowed to breed. Let's say you want a long-legged dog. You start by selecting the the most long-legged males you can find, and the most long-legged females you can find, then you let them breed. Out of their offspring, you then select the most long-legged puppies, and when they're grown, you let them breed. Keep this up for several generations, and soon you have really long legged dogs. The same method is used for whatever other feature you want the dog to have.
they have 4 legs because they have avolved from a tiny 4 legged creature, it was a good feature and so it stayed the same apart from the length.
Some distinguishing features of a 6-legged bug that looks like a spider may include a segmented body, multiple pairs of legs, and possibly the presence of silk-producing glands.

Scientists have discovered that whales' ancestors had vestigial hind limbs, now absent in modern whales. These vestiges are important evidence of a shared ancestry with four-legged land animals. The presence of these anatomical remnants suggests an evolutionary link between modern whales and four-legged animals from a common ancestor.

Yes they do use numerical taxonomy. They use this to classify things by their character states e.g a 3 chamber heart vs. a 4 chamber heart. They do this instead of classifying by their feature's e.g a 2 legged animal vs. a 4 legged animal. Hopes this helps :)
