The guy on the left is named Yapool. Courtesy of Club Tokyo - First appeared in Ultraman Ace and continued to appear in Ultraman Taro.
The bagged Marusan kaiju is Gohd from an unproduced episode of Ultraseven. There was an article in Hyper Hobby mag last year if I remember correctly.
Yapool also returns in the recent ULTRAMAN MEBIUS series and movies (with a recognizable, but updated, design). More more than you ever wanted to know, go here: http://en.wikipedia.org/wiki/Yapool
