> What information I can restore from these files? Tables structure at least?

depends on innodb_file_per_table setting. If OFF - the recovery may be possible - google undrop-for-innodb.
If ON - the data were in *.ibd files, they're gone after a DROP. The recovery is very tedious with not many chances and a lot of factors that can push it over fence in either direction.

Partially, the table structure may be recoverable from InnoDB dictionary that is stored in ibdata1. Check out sys_parser from undrop-for-innodb.

Good luck!

P.S. and yes, backup the database if it is of any value.
