Medieval coins to identify

First sorry for the quality of the coins.

1. best match I found is a Ferdinand Liard from Liege:


2. again, might be a Liard or some Hungarian coin but I got no clue


3.my only clue here is the crown so by best guess is Spain or Spain colony but really can't say


thx

Try Spanish Netherlands for the last one

thx, it seems so.

could it be this one ? ½ Liard - Albert & Elisabeth ?
