Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Nope. You should not even think of making a request/offer like that to a stranger.
You need to determine what the partition layout is for the new disk and make it match the others so you can fix all four arrays mdadm is showing, although probably only md2 and 3 really needs urgent attention.
Have a read through the Linux_Raid wiki for excellent background - there has to be a decent tutorial somewhere on the web too.

Reason: Make that four arrays (at least)
Suggestion for web-search: replace failed disk|drive raid* mdadm manage add
I *think/guess/vaguely-remember-from-15yr-ago* you could partition the new disk like:
sfdisk -d /dev/sda | sfdisk /dev/sdc (guessing sdc got replaced; be SURE first!)
And another *wild-guess*: (I don't know whether RAID1/4/5/6 matters here)
mdadm --manage /dev/md2 --add /dev/sdc (do NOT trust my *guess* [esp. md2] tho!)
Best wishes... (good *knowledge* [&info, not 'luck'] needed here!)
