Please Help - Update 6.1.21 To A Newer Version

[Enxuccio]

Hi to everyone.

I was at version 6.1.21 and would like to update it.

I would like to understand:
1) What is the latest version for my phone? (And where to find it?)
2) Do you want to recommend? (I read of wifi problems)
3) Can I install it directly from the version that I have?
4) Can I KEEP data?
5) After upgrading, I will be able to make updates via ota?

Sorry for all these questions, but I'm putting off for so long because I'm afraid to cause trouble.

thank you everyone

P.s. I attach a screenshot of my phone

Hello, download this ROM https://www.androidfilehost.com/?fid=24591000424943704, MIUI 8, I hope you have the bootloader unlocked and TWRP
Indications are: install without wipe, if he does not work well, proceed to wipe data, wipe cache and wipe Dalvik

I can not verify the update package
