UPDATED 4/17/15 8 PM EST
This is an exhaustive search but I feel like doing it now. This is uber-nerdy but I decided to catalog the different poses the Rangers do. This is more common in Super Sentai and ignored or not focuses on in Power Rangers. In Power Rangers, it is inconsistent. For example, I met suit actor/stunt man YasuhiroTakeuchi and he did the poses for each Ranger he ever did at PMC 4. These poses are usually in the roll call. Another tradition in Sentai is for the actual actors to do the poses 'de-morphed' in the finale. In the Disney Era, the individual poses slipped in much more (usually at the end of a Morphing sequence) as roll calls aren't common in Power Rangers as they are in Sentai. I'm going to cover the Sentai poses and compare to the American. Now I'll cover the Neo Saban Era, current era for Sentai.
Attention: This was done in 2015 when Dino Charge was on the air, it is outdated if you looking at it after its date.
2009/2011-2012
Shinkenger/Samurai/Super Samurai

Similar as he put his sword over his shoulder.

ShinkenPink/Pink Ranger
Similar as she had the sword on her shoulder but in different tilt and facing different direction.
Shinken Gold/Gold Ranger
Same pose as both hands on weapon to the side.
Hime Shinken Red/Red Ranger (Lauren)
Hime Shinken Red had two different poses, one with sword downwards or to the side. Lauren had her hand on one hip and sword up and away. Lauren didn't have much episodes so she didn't pose much.

Gokai Red would hold on to his GokaiSabre or do a 'cocky' pose. Super Mega Red had left arm bent near chest and right arm near side.
GokaiBlue/Blue Ranger
Both had a similar pose of one hand on head and the other behind the back. This was commonly seen when he transformed into other blue rangers.
GokaiYellow/Yellow Ranger
GokaiYellow's common pose was to put right hand bent and on her backside and left hand on her left knee. In Super Megaforce, she had a different pose where she had her left arm bent horizontal and hand on elbow of right arm bent pointing upwards.
GokaiGreen/Green Ranger
GokaiGreen had the common pose of wiping his hands on his pants which has been made fun of even on the show. This of course was not used for Super Megaforce. He had left arm bent horizontal and right arm bent up vertical.
GokaiPink/Pink Ranger
Ahim had too common poses that were 'princess likes' with both arms bent upward with hands on chest or hands bellow belt. Super Megaforce had different pose, left hand on chest and right arm out.
Gokai Silver/Silver Ranger
Gokai Silver had his arms out, Super Megaforce had the same pose.
2012
Go-Busters
This has not or will not be adapted but might as well cover.
Red Buster
Here I compare the regular series which didn't have the flash of usual Sentai against the Dobustu Sentai Go-Busters that made fun of the usual sentai. Red Buster usually had his right arm in front of his left arm and left hand in armpit. His "Dobustu" Red Cheetah had arms in the air.
Blue Buster
Blue Buster would just stand there while his Blue Gorilla counterpart would crouch and have a 'strong' pose.
Yellow Buster
Yellow Buster would grab her straps while Yellow Rabbit had her right arm up in the air with her left arm grabbing between her wrist and elbow.
Beet Buster
Beet Buster and Stag Buster would have their arms in front of their chests and two fingers out. Beet's Dobustu counterpart was very different.

Stag Buster
The real Stag Buster would have their arms in front of their chests and two fingers out while his Dobustu counterpart showed off his juice.
