@KrzysztofNowak,

Task 1

Find names in “Steven and Stephen bought a Stevensons&Stephensons brand stereo set from their stepfather Steve”

I used /(?<!&)\b[A-Z][a-z]*(?:\s+[A-Z][a-z]*)*(?!\S)/g to capture any name unless separated by an ampersand.

An alternative that only captures “Steven” and “Stephen” but not “Stevensons&Stephensons” or “Steve” is:
/Ste(?:v|ph)en(?!\S)/gi

Task 2

This regular expression, /\b[A-Z0-9]+\b/g matches robot names that comprise only capital letters or numerals.

Task 3

To find names in sentences without the word “gun” in the line, this regular expression works: /^(?!.*gun)([A-Z][a-z]+)/gm
