Alla ricerca di indirizzi di Mosaici a Yerevan

I have found that all of these mosaics are in Yerevan but cannot find specific addresses, and would like to see them when I visit in a few months. I know the first one is of Khachatur Abovian. The third slide is in an abandoned hotel but I don’t know where. The fourth is inside the building of the television station “Shogakat (Шогакат)”. The fifth is on the side of a factory. If anyone knows the location of any of these it would be greatly appreciated!
