Snakes and a few Baboons
Although I didn't photograph the info card, I tried to figure out which is which by referring to the museum's object lists
The relatively large statuette in the foreground may be:
OIM 8301 - Statuette in the shape of serpent - Abydos, Grv M65 - Protodynastic - Flint - 90l mm
The serpent amulets to the right could include:
OIM 10113 - Amulet of serpent god Nehebkau (aka Nehebu-Kau), Green Glaze Faience, 2 Hands To Head, Seated, Left Leg Advanced, Suspension Ring Back Of Neck, Saite, 45x20x7 mm,
OIM 17518 - Amulet of Nehebkau, Green Faience
OIM 17517 - Amulet of Nehebkau - Green Faience
I do have accession numbers for the three baboons, as seen in the card above them, from left to right:
OIM 4726 - Faience figurine of sitting Baboon with Front Paws Over Knees Of Hind Paws, Traces Of Original Color, Hierakonpolis - Protodynastic, 82hx42w mm
OIM 7970 - Faience statuette of Sitting Ape, Green Glazed Frit, General Form Rectangular, from Abydos Temple, Grv 69 - Protodynastic, 67x43x29 mm
OIM 7988 - Fragment of ape statuette, Head & Shoulders, Faience, Glazed Frit - Abydos, Temple, Grv M69 - Protodynastic, 95h mm

Descriptive list which gave more info about baboon statues

Nehebu-Kau: A snake-god, ‘He who harnesses the spirits’,
whose invincibility is a source of protection both in Egypt and in the Underworld.
(Source: _The Routledge Dictionary of Egyptian Gods and Goddesses_, by George Hart, page 99

In later depictions, Nehebu-kau was shown as human with a snake head, but earlier, he is shown fully snake. Nehebu-kau is known for the ‘seven cobras’ he swallowed. Jeremy Naydler in _Temple of the Cosmos_ also gives "Provider of Life-Energies " as meaning of Nehebu-kau's name, (page 36). Frankfort and Cramer in _Kingship and the Gods_ say his name can be translated as "Bestower of Dignities" or as "Uniter of the Ka's".

With all these attributes, it's easy to see why amulets of Nehebu-kau were so popular.
