Centurions armor between I and II century AD: evidences

[CaesarAugustus]

Just to go with what you have so far:

"Marcus Caelius, killed at the Battle of Teutoburger Wald, 9 AD, Lorica musculata"
Which has shoulder extensions to protect the upper arms similar to the Marcus Favonius Facilis a Centurion from Colchester. 
Clearly such an extension cannot be plate so cannot represent musculata, mail is a more likely option assuming the artist was trying to be specific.

"Titus Calidius Severus, around I century, Lorica squamata"
I wouldn't ague with that but it is a very simple representation if it is.

"Sertorius Festus, around I century, Lorica squamata"
For this you need to look at a much closer picture:

About Marcus Caelius, it is clearly depicted a cuirass of which the edges are absolutely evident.

The quality of the monument is really high and the torso is evident.


About Sertorius Festus, that is a plumata is an unsupported hypothesis, instead it is identical to another armor classified as scaled:

This is coming from a Verona museum.
