Here's my speculation for evolutions and possible English names:
Chiramii:Chilamy(romanization)
He'll evolve into a Normal/Ice type, getting an even furrier coat.
Munna:Levitap(levitate+tapir)
He'll stay Psychic, but I have a feeling this tapir is going to evolve into a floating, psychic bipedal elephant. A very bulky Psychic type.
Tsutarja:Vivy(viper+ivy)
I some have the feeling he will indeed become Grass/Flying, not Grass/Dragon. I remember hearing about a type of snake that can "fly" between branches.
Mijumaru:Aquotter (aqua+otter)
I see him staying pure Water when he evolves, though a Water/Rock or Water/Ground covered in shells, starfish shapes, and a sand dollar would be cool.
Pokabu
iglit (as suggested many times) He'll probably be Fire/Ground, due to the stereotype of pigs loving mud, though I can see him become Fire/Dark.
Gear:Gear/Gearr/Gearrs (in reference to the fact that there's two of them)
I think Gear will evolve into a Steel type Pokemon resembling an industrial machine of some sort, or some kind of gear-wheel mass.
Shimama:Zebolt/Zapra
It would be cool to see Shimama become Electric/Dark, as many others have suggested. It may remain pure Electric, and be a counterpart for Rapidash.
Meguroko:Sandile
Obviously, he'll remain Ground/Dark. I'm hoping he gets a thinner mouth and resembles a gavial or caiman. This little guy looks like a Pokemon that would spend alot of time digging underground. Its eyes remind me of flashlights.
Hihidaruma: Darumape
I love Hihidaruma. He's possibly my second favourite Pokemon now, next to Buneary. I could see him being a standalone Fire type, or one that evolves from a smaller daruma-monkey. Maybe a daruma orangutan?
Mamepato:Cherpidge
Mamepato is cute. I always wanted a classic example of a pigeon, and he fits perfectly. As some have previously suggested, I could see him evolving into a peregrine falcon, as they are also commonly found in cities. Note that the peregrine falcon is the fastest animal in the world when divebombing.
It can reach speeds of 370 km/h (231.25 mph).
