In my Java desktop application, i am using MySQL server for database operations but for some reasons i want to switch my application to work with HSQL database. My question is can we import the .sql file exported from MySQL into HSQL database to get the database structure as it is into HSQL database ? Thank you.
Yes, it's possible using a MySQL dump of your database, but you've to be carefull of some MySQLÂ compatibilities : http://hsqldb.org/doc/guide/management-chapt.html#mtc_compatibility_mysql.
Maybe some databases tools : https://en.wikipedia.org/wiki/Comparison_of_database_tools, or the http://hsqldb.org/doc/util-guide/transfer-tool-chapt.html can do the trick.

I have all my liquibase changelogs with respect to MySQL database now we are planning to move to MSSQL so when I try to run the existing changelogs which is working fine for MySQL is failing for MSSQL. Is there any configuration in liquibase to handle database migration?

addAfterColumn is not allowed on mssql
you can use dbms attribute and configure changelogs to be executed only on given databases.
I want to run the db dump code in the txt file while Spring boot application start. How can i do this?
otherwise i must copy-past and run db dump code to the mysql cli with manually.
if you want to LOAD data to database, i prefer to use Liquibase
you can load your data from .csv / .yml / .json / .sql
you can run it either before JPA Create Table or after create table.
So if you have a Team you all can have same data and table
if you want to DUMP your database, use liquibase too,
but why you want to dump your data if you have stable data master and it will automatically created everytime you run your app ?

You can with do it manually by running heroku pg:psql and then running the appropriate SQL statements. Or you can use a migration framework in your app.
For more information on running database migrations see the Heroku docs.

You will find the database scripts for a lot of the supported
databases in the DB subproject. The database scripts for PostgreSQL
are found in the folder '${JBPM_SDK_HOME}/jbpm-db/build/mysql/scripts.
The creation script is called 'postgresql.create.sql'. Using
DBVisualizer, you can load this script by switching to the 'SQL
Commander' tab and then selecting 'File->Load...'. In the following
dialog, navigate to the creation script file.

I want to export data from a Oracle database to a HSQL database to use in a test environment (which doesn't have oracle).
What would be the way to proceed?
You can create an ETL package using SQL Server Integration Services.
