I have one scenario below, how can we achieve.

City1,City2,Distance
==============
blr, pune,1000 km
pune, blr, 1000 km

As we have same data in 2 records but need to delete any one of the duplicate record.

Use the remove duplicate stage and use the hash partition, select the key column as 3 rd column (1000 km).
and select record retained = first , it will remove the duplicate record, you can also use sort stage for this.

If you have Numerical+Characters data in the source, how will you load only Character data to the target? Which functions will you use in Transformer stage?

Example : raje123ndh456ar

Code
convert(0123456789,,raje123ndh456ar) = rajendhar 

now it is converted to character string and we can load only character.

Ans--> Seq_File------>Sort------>Filter------->Seq_file

Filter Stage----> Filter by Key change column=1.
I think you will get the result.

From, change capture stage it connected to filter stage and then targets X,Y and Z. In the filter stage: keychange column=2 it goes to X [1,2,3,4,5] Keychange column=0 it goes to Y [6,7,8,9,10] Keychange column=1 it goes to Z [11,12,13,14,15] Revert me PLz

You can solve this question in easily way like.
First use the funnel to take the input data from different sources and used check box for unique data(No duplicate data) then
you can use transformer where you can apply logic like. @INROW

Using change capture stage:

File1(Master),File2----> change capture---> Filter ---->
T1, T2, T3
In Filter,
Change_code=1 then send then to T1-->(Insert records)
Change_code=0 then send then to T2-->(Copy records)
Change_code=2 then send then to T3-->(Delete records)
