Hi Greg,
For future reference on help identifying the SMD caps and their markings take a look at the post by Aaron Rollens found in link: Surface Mount Capacitors and their Markings
The first 623 50E cap could be 623uF at 50V. Unfortunately we do not have any at 623uF to offer in SMD package of electrolytics we carry so perhaps the 623 marking isn’t the capacitance value. I’m also not sure of the value of this cap. Like Steve said, if you can send a more clear pic of this cap it might help us better.
The second is likely 4.7uF 35V something like 565-EMVY350ARA4R7MD55GCT-ND which is 4mm diameter at 5.2mm height or 56-MAL215370478E3CT-ND which is 4mm Dia at 5.3mm height.
Third is likely 47uF at 35V though I found none at 6.6mm Dia, only 6.3 closest with height of 6mm: https://www.digikey.com/en/products/filter/aluminum-electrolytic-capacitors/58?s=N4IgjCBcoCwGxVAYygMwIYBsDOBTANCAPZQDa4ArAOwCcCAuoQA4AuUIAyiwE4CWAdgHMQAX0JwaiECkgYcBYmRAwADDQDMGkIxCt2XPkNGEwFFSqky5eQiUjlT6%2BNuZtInHgOFiQAJhUwktDSaFg2ivbKVAAEAK0AYi66biAAqvy8LADyqACyuOjYAK7cuMYgALRByFA8RQp2Dto%2BFb6Wtdz1tkoUzSIiQA
Last I think is 10uF at 35V but we don’t have any at that 4.2mm dia, the link below shows all in stock at 4mm diameter and 5.4mm to 5.5mm height.
Hope that helps. Have a wonderful day.
