What does the regex option do?

Turning on regex lets you search with regular expressions instead of plain text, so you can match patterns rather than exact words: any digit, any run of spaces, text at the start of a line, and so on. You can also reference captured groups in the replacement. With regex off, your search is treated as literal text, which is safer for ordinary edits.

Does it replace every match or just the first?

It replaces every match in the text in a single pass and tells you how many were changed, so you are never left wondering whether some were missed. There is no need to click through one match at a time.

Is the search case-sensitive?

You choose. By default the search ignores case, so "Cat" matches "cat" and "CAT". Switch on case sensitivity when the exact capitalisation matters, for example when editing code or proper nouns.
