Forbidden Siren help please

[jam master]

Hello,
I was wondering if someone could please help me with a few things in Forbidden Siren that are bugging me???

On Akira Shimura 'the old man with tha shotgun' level where you start in the firetower and you have to rescue girl, the hint to unlock another stage is to hide her in a special place - - where is that?????? Looked everywhere, but the right place!

Reiko Takato - In her level in the marsh with the lanterns, objective 2, what order do you have to light them in??????

Kyoya Suda penetrate the hive level, objective 2, Ive got down the sewer and am stood in front tha gate, but it tells me nothing Ive got will open the gate. Again, Ive looked everywhere, but the right place and cant find anything to smash the stupid door down! Any Ideas????

Last one for now,

Tamon matey with the hand gun in the abandoned (apart from a few undead people) Hospital, objective 2, get the album, Im supposed to stick the pipe out a window and pop it back through a slightly ajar window and float a key up in a grate. Found the 'ajar' window and grate, but cant seem to get the window upstairs, all the doors locked.

Any help would be gratefully recieved! Is a really good game, but can be well tricky, especially without a weapon!

THanks all
Cheers
JAm
