Flower Arranging is an art all its own and depends on a lot of things beyond just the vase, but I'll try to offer what help I can. For roses, especially that many of them, you're going to want something that still exposes around half of the stems or maybe a little more, which also gives them more breathing room and lets them fan out a bit. You also want to avoid a square vase, otherwise the stems will tend to clump in the corners, which isn't ideal. An Adrift Vase might work well with a dozen roses, since they come in a variety of colors and have a rather open 'mouth'.

First thing, Hindu deities do not hold roses in their hands, they hold a lotus. Two roses or lotuses would be a little too much as there could be other things that the deity could hold. So, each hand would hold a different thing. The things that they hold indicate their sphere of inflence or their specialization, for example, Saraswati holding a string instrument (Veena) or a book means she is the goddess of learning.
This is a question to which little meaningful answer can be given. The craft of making pottery to hold grain or oil pre-dates the Romans by hundreds or even thousands of years. It seems highly likely that the people who founded the city of Rome already had pottery skills, so that "Vases" as such were there from the start.
spill vases were small, usually porcelein, recepticles, to hold splinters or paper tapers that were lit from a hearth fire to transfer a flame to light a lantern or lamp. Most were figurines and sat on a fireplace mantel. The splinters were called spills and were used until matches were invented after the turn of the 20th century.
