Here are the answers to your questions:

5. Write down the formulas and names of four anions

Chloride: $\text{Cl}^-$
Oxide: $\text{O}^{2-}$
Sulfate: $\text{SO}_4^{2-}$
Nitrate: $\text{NO}_3^-$

6. Write out the chemical equation between magnesium and oxygen and name the compound formed.

Write the unbalanced chemical equation.
$\text{Mg(s)} + \text{O}_2\text{(g)} \longrightarrow \text{MgO(s)}$
Balance the chemical equation.
$\boxed{\text{2Mg(s)} + \text{O}_2\text{(g)} \longrightarrow \text{2MgO(s)}}$
Name the compound formed.
The compound formed is Magnesium oxide.

7. What are noble gases?
Noble gases are the elements in Group 18 of the periodic table (Helium, Neon, Argon, Krypton, Xenon, and Radon). They are characterized by having a full outer electron shell, which makes them very stable and largely unreactive (inert) under normal conditions.
