1: Obverse hard to read, reverse probably GENIO AVGVSTI… mintmark SMK, SMH or similar, A or Δ in right field. cf Licinius Cyzicus RIC 102  http://www.wildwinds.com/coins/ric/licinius_I/_cyzicus_RIC_VI_102.jpg

2: I'm guessing GLORIA EXERCITVS, two soliders with two standards. See https://www.tesorillo.com/aes/029/029i.htm 

3: obv: CONSTAN ... rev: ...STANTINI MAX AVG / VOT XXX / SM?? cf. N#119921

4: Constans / Gloria Ex. Can't make out the mintmark, might be SMK? (Cyzikos) http://www.wildwinds.com/coins/ric/constans/_cyzicus_RIC_viii_033.jpg SMN? (Nicomedia) http://www.wildwinds.com/coins/ric/constans/_nicomedia_RIC_viii_015.jpg or just about anywhere.
5: Looks like a gallic antoninianus with Sol (?) walking left on reverse. Cf https://en.numista.com/catalogue/pieces49474.html N#130134 …
6: Constaitius II / F.T.R. Fallen horseman, Constantinople cf. N#43772

Coin number 5 around 270 CE, the others from the first half of the 4th century.
