The average spider can have thousands of hairs on its body, with some species featuring over 100,000 individual hairs. These hairs serve various functions, including sensory perception, helping spiders detect vibrations and chemical signals in their environment. The density and arrangement of hairs can vary significantly among different spider species.
The hairs on a spider's legs are used primarily to smell. Spiders don't have ears, noses or taste buds, so they rely on these hairs to sense their surroundings, if something is moving nearby, and if something is edible. These hairs are called thrichobotria.

Tiny hairs lining each of their legs
A spider's sense of touch through specialized hairs on its legs is considered to be highly developed. These hairs help spiders detect vibrations and navigate their environment, aiding in hunting and detecting potential threats.
The spider you are describing may be a species of the orb-weaver spider, possibly the marbled orb-weaver (Araneus marmoreus). They are known for their yellow coloration, black markings, and red spikes on their abdomen. They are not considered harmful to humans and are beneficial for controlling insect populations in the environment.
Spiders have little hairs on their body that allows them to crawl up walls.
They are a defence mechanism. If agitated enough, the spider will dislodge some of the hairs with its legs, and 'flick' them towards an aggressor. The hairs cause irritation and, if aimed at the eyes, can cause temporary or even permanent blindness !
The kudus are two species of African antelopes, and both species have a coat of short hairs.
When nose hairs are plucked or pulled out, it can cause pain because the hair follicles in the nose are connected to nerve endings, which are sensitive to touch and can trigger a pain response when disturbed.
A spider does not stick to its own web for a few different reasons. Firstly, a spider's leg is covered in many little hairs that cut the amount of surface area the web has to stick to. Secondly, the hairs secrete a chemical that resists sticking to web. Lastly, spiders walk in such a way that allows them to slip off each strand of webbing.
I'm not sure. Arachnids (spiders) and insects (such as ladybugs, in this case) are two different species of insects in the kingdom Animalia. A ladybug may be able to inherit the possible appearance of a spider in some form (thorax-body, legs, possibly having small hairs) if it has a genetic mutation somewhere within its sequence of DNA.
