how i can test my web site on MS Edge web browser, if i do not have it installed

I have windows 7 and i got these 3 browsers installed:-

1. Firefox Quantum version 60
2. IE 11.
3. chrome 66.

now i want to test how my web site will looks like on MS Edge. but i am not sure what i need to do. so i have these 3 questions:-

1. can i install MS Edge and keep IE 11 ? so i will have 2 browsers types?.
2. is there any MS Edge simulators, i can use for testing ?
3. inside IE 11 F12 tools, i can find MS edge under simulators, as follow:- so will choosing this option mimic MS Edge?
