I'm not sure what you mean by the crosshair (because I played the game long time ago so I don't remember it dialogues), however tags is the pictures that you can paint on the wall or ground with the spray.

To paint tag on ground, simply equip the spray and press B button. Or facing the wall and press B button to paint it on the wall. Also if you already use Anima on the spray, it'll give element attribute to the spray. You can shot magic by hold space and press B button, or paint the tag then hold space and press A button to active tag explode (which necessary to solve some puzzle later).

To learn new tags, you must obtain them from the treasure chests in dungeons and overworld. Then open the menu, select the spray and check it with A button, you'll see the options to switch tags (in some puzzle, it require you paint correct tag to solve, other than that, different tag can give you different bonus when you paint and stand near it).

The hint is right there, the skull (left) and the lotus (right). Just paint them on the wall.

Of course you need collect those tags first, I don't remember where they are.

Go to I19. Save first (so you can load if need).

There is a ghost sitting on the bench at Seaside Ruins (L16). However she'll vanish immediately if she saw you. That's why you must go to K16 then enter L16 from the north. Approach her  from the back to unlock the scene. 

I think she only appear one time per day at night time, so if you enter from the south and she vanish, you must load or wait until next day to try again.

Ah, thank, I'm not reach that spot yet, I play Nyx route first because it's easier. In Sasha route I only defeat the Beelzebub and stop there.

I read some people say in some conditions you can get different scene but I guess it's not:

You can time escaping via an attack to the last possible moment before game over to have your character penetrated. You actually get a different picture in the inventory menu if that happens a couple of times (at least while naked).

I'm not get it. How can you escape when you get banged? It's gameover isn't it?

I tried to wait until the Z button disappear and use X to escape for 5 times in a row but nothing happen.

Queen Bug? If you mean the Beelzebub boss in this room then there is a cheese method to defeat her, just hide behind the tree like this pic, then she will stuck in the red circle spot, and you can use the gun to shot her to dead.

Unfortunately, I can't remember exactly where is it, but it's just somewhere in that Hoarder's Passage area. I cleared everything except that room in pic 1.

How about show your map? Then I can see which room you're not cleared yet and help you solve the puzzle in that room.

There aren't anything after that though, the next area still in developing.

Pic 1 is the right house in the Hoarder's Passage.

You can buy second anima from witch shop (which located inside the Hillside Cave Q14).

Can anyone help me open those doors? :(

Well, the advice above is correct but not clear, I guess you just didn't know how to "active" the  spray.

After put the tag on that pad (like your picture), you must press Space+Z to active it (again, Space+Z, not Space+X). A lightning will strike down that tag, then the  red dot will turn green and you can pull the level.
