https://www.NGCcoin.com/price-guide/world/That is my go-to for all world coins. It gives you a good index, but keep in mind that catalog values for world coins are fickle at best--I have seen $15 coins go for $0.99, and I have seen $5 coins go for $15. On average, for coins that are not "Rockstars" or very popular series, I would multiply the value listed on NGC by 0.5 for coins made after 1950 and 0.75 for coins made before 1950.
That said, all of your coins appear to be uncirculated. The numbers don't mean squat if your coin isn't in a slab (fee for one coin would cost more than the combined value of all of these) so use MS-60 or 63 as a reference point for all of your coins. The Cyprus half Piastre is probably the most valuable in the lot, but the Austria 2 groschen is the most attractive (I have several in similar grade, so high grade doesn't add much to this coin).
