Hello... Perhaps I can answer.
If you're talking about "figurines", many different companies have made those of varying characters in a number of styles and poses.
If you're talking about the "action figures" that were to be made and released by Palisades Toys... Well, I have some bad news for you.
In February of 2006, Palisades Toys went bankrupt and got bought out by a different company. The first set of Sesame Street action figures were made at the factory but were never imported nor released for mass market retail. Unless you get really lucky and find some ubber-cool prototypes on eBay, I'm afraid these will never see the light of day.
Hope this helps, have a good day.
