Answer 1

One problem is that you have if deptno=10 without a following then. Another is that the elsif in the same if statement also lacks a then. In PL/SQL an if statement should generally be:
IF condition THEN
block_of_code;
ELSIF condition2 THEN
another_block_of_code;
ELSE
yet_another_block_of_code;
END IF;
Documentation here
In addition v_cursor= 'select * from '||v_table||''; should be
v_cursor := 'select * from '||v_table||'';
This is because the assignment operator in PL/SQL is :=, not = as it is in C, C++, Java, C#, etc.
Finally, it appears you're missing one END statement at the end of your code.

Answer 2

I think, in your code:
if deptno=10
v_table=abc;
v_table1=abc1;
elsif deptno=20
v_table=xyz;
v_table1=xyz1;
end if;
The assignments should be ":=" instead of just "=". ALso, assuming "abc", "abc1" etc are literals and not variables, try enclosing in single-quotes:
if deptno=10
v_table:='abc';
v_table1:='abc1';
elsif deptno=20
v_table:='xyz';
v_table1:='xyz1';
end if;
