This simply requires you to

a: Look at the periodic table - that will answer A, C and D
b: Find out the characteristics and Periodic table positions of metals, metalloids and non-metals - That will allow you to answer the rest.

That's all...

There's LOADS of interesting stuff to be learned from just looking at the Periodic Table. If I tell you the answers you learn nothing - if you look at the table then you may learn a lot.
