Answer 1

This one should find all o...r@ patterns, but you need to delete the spaces inside the regex.
The problem is, though, that consecutive emails have no precise ending, unless you are sure they are always beginning with the capital letter, so you can use it as a rule.

Answer 2

Omar o \w represents a "word" character, so any of the a-z, A-Z, 0-9 ranges or an underscore (no spaces!). There are only two strings meeting that criteria and so they are returned.

Answer 3

That's because .+ is greedy and looks for the longest expression meeting the criteria without distinguishing between actual characters. And so the longest possible is the whole string from Om |ar@ until Amer| @gmail.com
