Seems you do not know what are you going to do.
- zip files you have on your local
- go to your hosting ftp (or cpanel with files)
- extract this zip (should contain osclass, theme, plugins ...) into root folder (or folder for websites)
- export your database on local
- go to your hosting db management
- create 1 new database (good would be with same name, db password, ...)
- import tables from file you extracted on local
- change config.php to stable connection between osclass and your database
You should be done
