All seven weapons have 4 different levels which have different damage stats, these are meant to help balance them for later sectors.
There are 3 new pistols and 4 two handed weapons.
Rokstedi
Lobster
Gerund
Mossington
Kalt
Tokmak
Sea Eagle
All five weapons can be purchased from an Ark Vending Machine, which can be crafted for 1 pixel in basic crafting or at a crafting table. Be warned that the prices are quite hefty, especially for higher level weapons.
Creds to Izeck for helping me balance the weapons.
