need some more help

I bought various gingers years ago and now I'm trying ID them. Can anybody help me ID the following three?

Fred

and this. I saw a shampoo ginger discussion here. Is this the same?

a closeup

and a red one

with closeup

Costus woodsonii for #1
2 is Shampoo Ginger/Pinecone Ginger Zingiber Zer.......
3 looks like Hedychium coccinea

Couldn't find any red Hydychium coccinea but Red Butterfly Ginger, Scarlet Ginger
Hedychium greenii seems like a better match even though the plant files show something less red then mine.

Now I have another problem. This plant resembles a blue ginger but I didn't plant it and it sort of looks like a weed among my Ixora. I do have blue ginger about 200 ft away behind the house in fairly deep shade. They are tall and have big blooms. Can the plant shown here be a blue ginger? Or what?

this is my 'other' blue ginger.

the leaves sure look the same

yes it is blue ginger(not true ginger) is Dichorisandra thyrsiflora

Donna,
the Pic where the ixora also grows?

yes Fred
