Help Identify Roman Coins

If anyone can help me identify some of them, they are in terrible condition.

Coin 1, yellow coin. It's possible to identify some letters.

(Will try to fix this)

Diameter around 26/27mm

Weight 10.4 grams

Coin 2.

Diameter around 24/25mm

Weight 5.8 grams

Coin 3

Diameter around 24/25mm

Weight 9.8 grams

Coin 4, Yellow coin, and i think its a woman, it has a hair bun

Diameter around 22/23mm

Weight 3.9 grams

Coin 5

Diameter around 24/25mm

Weight 7.6 grams

Coin 6, it has a crown or something, an can se a NE on left side of the bust 

Diameter around 26/27mm

Weight 5.8 grams

Coin 7, big and heavy, can see TON or ΓΩN on left side of bust

Diameter around 27/28mm

Weight 24.8 grams

Coin 2 has a portrait similar to Hadrian

I was still able to get an approximation of the Coin 7, based on size, weight, and some of the characters; I believe it's similar to this one.

As for Coin 4, I believe it's similar to this one from Faustina II.

It's quite sad to see coins with so much history in this state, but it's part of receiving excavation lots; not all soil can preserve their quality.

Coin 5- maybe Marcus Aurelius 

Coin 6 is Nerva or Trajan, was able to see NER*A

Coin one- maybe caracalla?
