Spiders are arachnids and so are scorpions, mites, and ticks.
Scorpions, obviously, but also harvestmen (not Aranea, other group more closely related to scorpions), and even horseshoe crabs.
No they aren't. Cave spiders and camel spiders belong to different taxonomical orders.
No, spiders and scorpions do not belong to the same phylum. Spiders belong to the phylum Arthropoda, class Arachnida, while scorpions also belong to the phylum Arthropoda but are classified in the class Scorpiones.
First of all, although they are horrifying, they are not even spiders at all. They are called wind scorpions. wind scorpions are in the same group of animals as spiders, mites, ticks and true scorpions, but there are several differences between them. They do not carry any venom and could not kill a human. However, it is easy for a camel spider bite to get infected which could later lead to death if left untreated. Mostly, they eat small rodents such as mice, or lizards. They are only called "camel spiders" because they live in the desert, just like camels do and, contrary to popular belief, only can have a body size of up to 6 inches. They legs often can get longer though.
They are both part of the same species group
Scorpions ticks mites etc
Scorpions fall in the arachnid family (same family as spiders, ticks, mites etc) That being said, all scorpions have 8 legs.

Spiders and scorpions both belong to the arthropod class Arachnida (arachnids) and are not insects (they have 8 legs).Spiders are of the order Araneae and scorpions of the order Scorpiones.
No, and incase you're wondering, all the names you mentioned above refer to the same arachnid, the Solifugae. These are not spiders, but the two share many similar features such as eight legs, obvious fangs, and two separated body parts. The Solifugae is not venomous, nor can its bite be lethal. You should not handle Solifugae however, because their bite is said to be very painful.
Scorpions have four legs and a tail that they can move around with. They walk just the same as other creatures with four legs. Similar to spiders.
