I want to add another Ssd to my and I was to know will this particular data cable will fit? it's a square mini 4pin cable. I'm not really sure whether this will fit or not since I heard there's also standard size so I don't know which one my system has whether it's the mini or standard.

Impossible to tell from just photos.
I did a Parts search, and when I Google "54Y9339", it appears to be a fairly common part.
So, I have this lenovo m900 SFF and I'm having an issue with finding the right sata power cable for it since it's a proprietary cable ( square 4 pin ) so I saw this particular one 8 pin dual sata cable. Is it safe to use this for my m900? or will this cause a problem? 
I don't see how an 8-pin plug will work in a 4-pin socket.
54Y9339 is common part, used with M900 and earlier generation SFF and Towers.
So I have a Lenovo M900 SFF. and I have a spare SATA 4pin square power connector from the Lenovo M83 can I use the ones from the M83 for my M900?
Yes, you can. As I wrote above, and if you Googled the part number, you would see it was used with M83.
