5000-30,000 depending on where you live , and the child's needs .
If it's a private adoption like your step child you can do it without a lawyer so then you just pay small fees and if you adopt from foster care the cost could be nothing but a few hundred because it's so rare than people adopt teens. Talk to the social worker handling the child's case.

'Signing over their rights to a child' sounds like adoption here. Most states have laws set about who can adopt. Usually people over the age of 25 and / or married couples. Not to say that you cannot adopt under the age of 25, but I do believe that you must be at least 18 to adopt a child in some states. Minors under the age of 18 are not considered adults, and therefore cannot adopt children.
it depends where you buy them
Not as much as it cost to adopt a dog.It will depend on what type of kitten. There are some pretty expensive cats out there.An average kitten will cost about 15-30 dollars.
