For #1 the answer is the site may not be trustworthy, and you risk identity theft. If you are not sure a site legit then don't trust it. Some sites can easy to tell if they can be trusted by the amount of detail put into the site itself, but others are not so easy to tell. In general, if a site does not have https:// in the web address, but instead has just http:// (no "s" in it) then don't trust it.
For #2 the answer is to use<span> a secure browser. If the browser you are using is insecure then the info you put into a site can be compromised and stolen by the browser itself because it reads all info put on it.
For #3 the answer is i</span><span>t has a secure payment page. Again going back to the https:// vs. the http:// if the page that you pay on is not secured then your credit card info can be stolen when put in because the site without a secured page will allow others with access to see your info.
