The last unidentified coin is judging from the radiate crown a third century antoninianus. The reverse is in my opinion Apollo standing left APOLLINI CONS or APOLLI CONS however multiple emperors used that reverse and there isn't much of the obverse left. Here's a similar coin of Claudius II: https://www.numismall.com/products/v5937

Thanks to cro321 as was not sure what was behind the person on the reverse; it is a lyre. http://www.wildwinds.com/coins/ric/quintillus/RIC_0009_N_retro.jpg
