1. K is always +1
O is -2
To find the state of Mn, you add K and O together as following:
4x(-2)+1+?(Mn)=0
-7+ ?(Mn)=0
Mn=+7
I hope this will help you solve the rest of the problems. If not, ask me and I will gladly try to explain it better.

Example #2.
O=-2
2x(-2)+?Ni=0
-4+?Ni=0
Ni=+4
Thought I as well do one more (:
