7 Coins From The 1600s? Need Help Identifying

I'm pretty sure at least some of them would be from Poland-Lithuania. I'm not sure about some of them though.

These copper coins are known as "boratynki" (singular "boratynka"), after the Polish-Lithuanian finance minister Titus Livius Burattini, who introduced this issue of "solidus" coins in full copper instead of previous debased silver.
(The English Wikipedia article for Titus Livius Burattini doesn't mention this at all, incidentally; his list of other - mentioned - accomplishments, though, reads like a quite peculiar biography.)

These coins are very common, and thus very cheap, since there were an awful lot of them made (said to be over a billion).
The type for Poland shows the Polish national eagle, the type for Lithuania shows the Lithuanian national horseman (both designs, with minimal variation, are used on the respective countries' currency to this day).

This type wasn't struck especially carefully, and is often found in very bad condition (worn and/or corroded), so they are less common (but still not very valuable, due to sheer amounts) with visible dates, or visible mintmarks, or especially both.
Doesn't apply to any of your examples, obviously (though I think I can see the TLB mintmark on one of them - TLB, for the record, stands for Titus Livius Burattini).
