Manipulating and populating the data from sheet X to sheet Y using dynamic VBA script

Hi guys, just wanted to ask for your suggestions on how to approach the 2 following issues in terms of writing the script that I need to populate data from sheet X into template within sheet Y.

1) Multiple items divided by “;” are in column B within sheet X and need to be split once moved to template Y, but in the separate row of the same column. E.g. x;g;h; in the cell B2 (sheet X) would need to be populated into template Y as B2 for x,B3 for g, B4 +h. How should I go about it?

2) I have a shortcut of signs in the identification section of the sheet X (lets say in column D), the values are in the following format (all in D2): (ID):1234;(IB): 321; (IC):213.
Now I need to move the following to template Y where ID = Identification; IB = Internet barcode and IC = Identification of court (as per the created lookup table). How do I write a code that reads from look up table and populates this data into new table as new expanded/ expressive form? E.g. (ID):1234;(IB): 321; (IC):213 in sheet X -> (Identification):1234;(Internet Barcode): 321; (Identification of Court):213 in sheet Y (e.g. also column D2)

3)This is related to issue 1..How do I copy multiple records from sheet X populating them into Y, if I want the next record to be populated into A column and the first (full) available row? Given the scenario in section 1 (i.e. according to example given above, the new record would start in A5 as x;g;h was moved to B2-B4 in template Y).

Hope the above makes sense!

Thank you so much - Any guidance/help would be appreciated!
