Answer 1

For comparisons involving multiple fields, it's more like bottom up approach, you start comparing 2 fields, then the result with 3rd field then the result with 4th field and so on. So, your query should be like:

      <And>
     <Eq>
        <FieldRef Name='fieldName1' />
        <Value Type='Text'>value1</Value>
     </Eq>
     <And>
        <Contains>
           <FieldRef Name='fieldName2' />
           <Value Type='Text'>value2</Value>
        </Contains>
        <And>
           <Contains>
              <FieldRef Name='fieldName3' />
              <Value Type='Note'>value3</Value>
           </Contains>
           <And>
              <Eq>
                 <FieldRef Name='fieldName4' />
                 <Value Type='Text'>value4</Value>
              </Eq>
              <Eq>
                 <FieldRef Name='fieldName5' />
                 <Value Type='Text'>value5</Value>
              </Eq>
           </And>
        </And>
     </And>
  </And>
