Help identifying these glass pieces?

[vint700]

Dear community, 

would be so happy if anyone has any info on the pieces below... 

I have done a lot of research online yet it seems difficult to me to find out who made them... I believe they are all italian Murano glass. 

First one is probably "pulegoso" amber glass with 3 holes (forato) and a double neck

Second one is a ruby red glass vase with 4 handles

Third one looks like a pulegoso vase, similar to some Toni Zuccheri pieces for Mazzega?

Fourth one is a glass lamp probably made out of murrine, similar to the Nerox series by Fratelli Toso?

Any help would be very much appreciated! 

Regards, J.

Third one is a German vase, from Spiegelau, just found out

Hard to tell without pictures of the bottoms. very critical in reviewing glass.  You might have better luck on ID help in some of the Facebook groups dedicated to glass.
