Answers:

nested if with atleast 2 or 3 levels are used generally in asynchronous counters and asynchronous digital system.
example:

if(clk=clk'event and reset=0)
{
if(q1=0 and q2=1)
y=1;
else
y=0;
}
where q1 and q2 can be the output present states of 2 flip flops connected asynchronously and the final output y is dependent on the flip flops like the nested branches.
