The bivalves are (from L to R, top to bottom):

Lampsilis teres (Rafinesque, 1820)

Utterbackia peggyae (Johnson, 1965) if from the Apalachicola system, U.
peninsularis Bogan & Hoeh, 1995 if from peninsular Florida.

Can't tell without seeing the inside. Maybe Villosa villosa (Wright, 1898)

"Elliptio buckleyi (Lea, 1843)" - probably not a real Elliptio, and this
"form" is likely a distinct species - tryoni Wright, 1888

Shell appears to be at an angle, but probably another U. peggyae

Lampilis teres - the rayed form sometimes called fallaciosa. Also the
"floridensis" of authors, not of Lea.
