The male dolls you have seem to be Shou from Angel's garden in the action type body, Takumi, Izumi's boyfriend in the gray vest outfit, the nude platinum blonde seems to be Charles (prince) Licca's cousin, the ones in the bag are 3 versions of Pierre Licca's dad and 2 Jeff dolls...

The pregnant doll is not Jenny, it's Licca as an adult the baby you were supposed to mail in a coupon that came in the doll box and they would send you the baby by mail and along the baby was a key to unlock the pregnancy belly... The baggy with the slippers and accessories belongs to the pregnant Licca and the thing you thought for her hair was a maternity panty I think The one with extra long hair is Izumi Licca's best friend and girlfriend of the boy in gray. The rest are different Jenny dolls and some of Licca's kindergarten friends. I think you overpaid a bit on the dolls. But as long as you are happy and the dolls you got are what you wanted who cares honestly?... The prices you saw for the prince dolls might've been high because they were new in box dolls, that makes a huge difference in the price as well as the condition, dolls with smoke smell and out of box should never be more than 20$ because they're considered ruined and lost all their resale value. Condition and scarcity are the factors for high prices, just like with any other doll. You're more likely to get better deals on Japanese fashion dolls on Yahoo Japan and Mercari Some Jennys and vintage Liccas pre-1980 can be expensive regardless of condition but for 1980 and forward loose dolls should be in pristine state to be expensive otherwise they're scamming you.
