Display random variables from 2 different modular pages

Hi,
I have 2 different modular pages
The 1st page is members.md and this is an exemple of what it contains
1:
name: member1
title: title1
2:
name: member2
title: title2

And another page others.md:
1:
name: other1
title: other_title1
2:
name: other2
title: other_title2

I wanna display in members.html.twig a only 1 name and title randomly from members.md or others.md:
How can I do it in twig and is it possible to read data from another md file in grav ?

Thank you in advance
