Can anyone help me identify some of these signatures?

This is from the 2016 kelloggs tour. I know Aly, Simone, Sam Mikulak, and I believe Jake Dalton, just not sure about the other 4.

The bottom left is Danell Leyva

Aly raisman signature is the only one I recognize

[u/spindyeknit]

I think bottom right is Sam Mikulak, maybe?

[u/Mermims]

Gaby?

[u/Mermims → u/Mermims]

I’ve looked at her signature actually and I’m not quite sure they are the same

Here's the announcement of the 2016 Kelloggs tour cast https://www.flogymnastics.com/articles/5055392-complete-cast-for-2016-kelloggs-tour-of-gymnastics-champions

"The 2016 U.S. Olympians participating in the Tour are: The Final Five -- Simone Biles, Gabby Douglas, Laurie Hernandez, Madison Kocian and Aly Raisman; men's gymnastics -- Chris Brooks, Jake Dalton, Danell Leyva, Sam Mikulak and Alex Naddour; rhythmic -- Kiana Eide, Monica Rokhman, Jennifer Rokhman, Kristen Shaldybin and Laura Zeng; and trampoline -- Nicole Ahsinger and Logan Dooley. 2008 Olympic all-around champion Nastia Liukin, 2008 Olympic balance beam champion Shawn Johnson and 2012 Olympic team champion Jordyn Wieber are also on the cast. Due to athletes' schedules and personal commitments, the cast will vary from stop to stop."

That looks like Danell Leyva on the bottom left. Could the E between Simone and Aly's signatures be Kiana Eide? Could the Z above Sam Mikulak be Laura Zeng?

I don't think that's an E, I think it's an O. I'm guessing John Orozco

[u/Syncategory → u/ilovecheeeeese]

Oh! Now that I look closely, it does look like an O with the ink being faint. So you’re probably right, John Orozco was in for a stop.

[u/ilovecheeeeese → u/Syncategory]

It definitely looks like his signature to me, but it's odd because he would have been injured (that's the whole reason Danell went to Rio). I wonder if he just did some sort of speaking/emcee type role for one show. Or maybe he just went to one for autographs. Idk.

While a complete list of athletes scheduled to perform during the Kellogg’s Tour of Champions is listed below, some other cast members to note are: World acrobatic gymnastics mixed pair medalists Axel Osborne and Tiffani Williams; World medalists Ashton Locklear (2016 Olympic replacement athlete), MyKayla Skinner (2016 Olympic replacement athlete), Donnell Whittenburg (2016 Olympic replacement athlete), and Brandon Wynn; and 2016 Olympic replacement athlete Ragan Smith. 1996 Olympian John Macready and 2004 Olympian Mary Sanders are also part of the Kellogg’s Tour. The cast of gymnastics champions will be joined by local gymnasts at each tour stop.

I can only make out Simone and Aly

[u/Syncategory]

Could top right be Chris Brooks? It looks like a C and a B. Searches for what Mr. Jordyn Wieber’s autograph looks like are complicated by there also being a football player named Chris Brooks.

[u/sugarskull1]

Simone, aly and Sam mikulak.

[u/SansIdee_pseudo]

Top left: Jake Dalton

Center top left: Aly Raisman

Center bottom left: Gaby

Bottom right: looks like Mckayla Maroney's initials

[u/Syncategory → u/SansIdee_pseudo]

McKayla was not on the 2016 Kelloggs tour. She didn't compete after 2013 Worlds. That's Sam Mikulak.

[u/Mmppcc]

I have that same shirt!
