The challenger breakers are dangerous. Don't use them. The Connecticut Electric are legal copies of out of production breakers and may be dangerous. Don't use them. The Siemens D are fine if they are actual Siemens (not fine other brand claiming to be compatible) and your panel lists that type.

Bottom line is that ordinary (as opposed to GFCI or AFCI) breakers for most panels are 5 to 20 dollars each, depending on brand and single vs double and simply not worth the risk of buying any way except new and from a reputable source. And in any case you need to make sure you get exactly the right type.

As far as everything else, post a new question with a picture of your panel.
