#3. the white bowl with red/orange interior and gold flake throughout: most probably Barbini.
#4. the aqua bowl with quilted texture and aventurine infused exterior:
possibly F Toso?!?
#s 1,2 & 5. i dunno. i've seen many pieces similar to these but never one that was unambiguously attributable. most, if labeled at all have a "genuine venetian glass/made in italy - murano" sticker which, in most cases, gives us no clues as to who might have been the maker. these are generally called "generic" (which sounds moderately offensive i know, but merely suggests that, though it's presumed to be Murano glass, the maker is indeterminable at this time). of course, they may only be unattributable to me, in my limited knowledge.

it's quite possible that someone else will come along who can attest to these pieces lineage.
have a beautiful day!
