The Count Needs a Lot of Help!

[The Count]

Hi guys, I rully need some help from all of you, old-schoolers and new-schoolers alike! Went over to www.imdb.com and found the following new entries for SS characters, both human and Muppet. What I need from you guys is confirmation that these characters rully indeed did appear on SS throughout the years. If so, please also provide a full descript of what they looked like including their regular clothing, cause I'm visually challenged and thrive upon the descripts of others.

Here's the list, along with what years they were on the show.
Alex (Alexis Cruz, 1990-1991)
Ellie Jane (Heather North, 1978-1990)
Grouchkateer (Josh LaBove)
Hans Heinz (Arte Johnson, 1970)
Harriet (Clarice Taylor)
Is this the correct name of David's Grandmother?
Jelani (Eugene Byrd, 1987-1990)
Jesse (Randy Pearlstein, 1994-1995)
Kim (Kim Raver, as herself, 1975-1978)
Leon (1985-1987, performed by Richard Hunt)
Is this the same character I've already listed in the Muppet Listings as "Leo the Party Monster"?
Lexine (Lexine Bondoc, 1992-1999)
Miles Robinson (Olamide Faison)
Is this the newest actor to portray the role?
Numbers (Lauree Dash, 1997)
Rhasaan (Rhasaan Orange, as himself, 1978-1983)
Please post your replies here in this thread or contact me directly via the forum's mailer. I'd rully appreciate any help in identifying these characters before I go public with ML 12.
Thanks and hope to hear from you guys soon!

Sorry, me either.

well Kim Raver is today on the series 3rd Watch and was 1 of the kids. the lady who played David's grandmother 1st appeared in the 70s and you'd see her come on every once in a while. i know there was a puppet naned Leon that i don't think lasted very long. don't know about everyone else.

So, that's a "Yes" for adding Kim.
mikebennidict, if you know, what did Leon look like? And is it the same character as Leo the Party Monster? If not, then how do the two characters differ from each other?
Also, is Harriet indeed the name of the character of David's Grandmother?
Hope to hear from you soon and have a good night.
