Most Servants can have multiple classifications (e.g. Cu can be summoned as a Lancer and/or a Caster). My questions, in terms of a Fuyuki Grail War with only seven classes, are:

1) Can a Spirit with at least two different classes be summoned into the same Holy Grail War as long as they are different classes? For example, can two Cus be summoned, one to fill the Lancer class, and the other Caster?

2) If so, does that make the each class of the Spirit totally different beings? According to Caster Cu's and Caster Gilgamesh's pages, they have slight alterations to their personalities due to being a different class.

3) The phrase "so (Servant's identity) became (class) because (reason)" has been tossed around, so does that mean that Servants can change their class if they want to (specifically ones who do not have a Noble Phantasm to do it)? On Caster Gilgamesh's page, it is stated that he eventually "reappears as an Archer."

Side note: I have read the Classification section on the Servant page, and the Holy Grail War (all five Fuyuki Wars and Grand Order) page over and over, but none of the above are specified or mentioned.
