Can someone identify these species/hybrids?

These photos are taken from a Japanese Nepenthes site (S-Yamada) on which they are simply listed as "Nepenthes sp".  I wonder if anyone could help identify them.  I've got a few ideas of my own, but would first like to hear what you guys think.

"Nepenthes sp" from the Philippines:

Look forward to hearing your views,

Sorry for posting this topic twice. I've been having some trouble with my internet connection. Please feel free to delete one of the copies.
 
The second Philippines plant looks kind of like faizaliana but I would need to see more of the leaf to be sure.

The final one looks more like a truncata x ventricosa hybrid to me

No clue on the others
 
Agree with Pyro on that last pic. It looks very similar to our large ventricosa x truncata, which we got from a good friend. This plant may be from tc.
The sumatran species is a dead ringer for a plant we got from Bruce Bednar many years ago. Bruce simply called in sumatran species, because it had been collected near Sibolga. We think its a natural hybrid, possibly with gracilis. The pitchers are too big to be pure gracilis, so it may be part reinwardtiana??

Could be N. mindanaoensis

N. petiolata new species

Not sure

Perhaps N. petiolata

"Nepenthes sp" from Sumatra:

Looks like an alata

Simply labelled "Nepenthes sp":

Could be N. ventricosa x truncata or vice verse
But also resembles the natural hybrid of N. truncata x petiolata (mindanaoensis) too!
 
"Nepenthes sp" from Sumatra:

http://yamadanouenn.hp.infoseek.co.jp/sc01426.jpg

is not an alata...N. alata doesn't grow in Sumatra. Check out a pic of our plant.
N.%20Manny's%20eustachya%208-31-04.JPG

To make a very long story shorter, this plant was given to us a N.eustachya... but it is clearly not.  The vine has a gracilis growth habit, but the traps aren't right for gracilis.  We think it's gracilis x reinwardtiana or something similar.      
A lot of the unknown plants in those pics could be natural or man made hyrbids, some of the smaller plants are still too immature to make an id.
 
N. mindanaoensis is not a natural hybrid between N. truncata and N. petiolata.

But also resembles the natural hybrid of N. truncata x petiolata (mindanaoensis) too!

This isn't meant to be implied as a result of the two crossing. Its merely to state that at one time petiolata was a synonym of mindanaoensis, so whichever the correct plant was used, its in parenthesis as a synonymous name and doesn't imply that petiolata is the same specis as mindanaoensis. This is why the parenthesed name comes right after another species epithet.

Ah.. did a little research and see what your saying Michael. Yes indeed the natural hybrid was listed as N. truncata x petiolata at the time N. petiolata was a synonym for N. mindanaoensis. Alot of confusion around the Nepenthes from that area and still is today! Fortunately the real N. petiolata is in cultivation finally!

Yes, and I still see truncata x "petiolata" on people's lists occasionally, lol.

Cheers,

What makes even more confusion is that many people who sell truncata x petiolata actually has bellii x truncata instead. A very different plant, but just the name game thing.

I retract my earlier comment, I just went to the source page and looked at other pics of the same pitcher from a different angle - definitely not fusca. I now just put it in that jumble of species from The Philippines that could be alata but maybe isn't. Definitive, eh?!
