Restore SQL Server database from .sql files
So you just need to execute the collection of schema scripts to recreate your database? You could execute them one by one or create a batch file and use SQLCMD to execute all script files in directory

for /r "%ScriptPath%" %%X in (*.sql) do ( 
   sqlcmd -S%ServerName% -d%DBName% -b -i "%%X"
)
