So I have a few medieval coins I'm having some trouble identifying. I've just been beating my head against the wall with these lately, so any help on these would be greatly appreciated!

This appears to be a denier from the Bishopric of Lausanne around the 13th-14th century, resembling something like this:

This one I have not been able to find much on. One side has a crown, and I can't tell what the letters underneath are. DX/D'X/JO'X/JOX all seem like decent guesses. On that same side, the text seems to read MARIA + ?MIPUS. On the opposite side, it seems like it says INX * MEDIO and then something else. I have not had any luck with this one at all.

This one looks a lot like these Duchy of Savoy 1/4 Grosso from the late 1500s:

I have a couple of these and the FERT is clear, as are the double lines above and below. It almost looks like + EPAI LIBER * DVX and pretty clear A DOMI + on the other.

Some of the text on the side with the cross is legible. I see SIT:NOME:DHI:DEI:H)P:XPI. In the next ring it looks like ROLUS * REX. On the opposite side, it almost looks like SAVENS + DA. I can't quite make out the features on the indside.
It kind of looks like some of these gros tournois and others:
This is the one that it looks closest to, but I'm not seeing LVDOVICVS anywhere. It appears to be someone else.
https://en.numista.com/catalogue/pieces57848.htmlThese others are similar, but the Louis appears to be the closest:

I haven't had a whole lot of luck with this one either. It appears French due to the fluer de lis on the portrait, but I haven't come across any French coins yet where the portrait extends through the lettering. I have seen that on some English and Spanish coins, but nothing yet French. The obverse appears to say something like CICIERG?+?S?P. On the opposite side I m seeing COMES : PRO?HLIG+.

That's it for now. I have 5 or 6 others that I'm working on. If I don't get anywhere tomorrow, I may start putting those up as well. Thanks for looking, and thanks for any help!
