At most, 10; this is because you may end up activating all 5 of both your opponent's and your own cards each, but cannot play any more and have them activate that same turn.

seto, kaiba and pegasus give out really good trap cards like crush card and such.
Yes, as long as the spell card is a Quickplay Spell, and the trap card is not a Counter Trap. So you cannot chain Monster Reborn to any trap. Nor can you chain Book of Moon to a Counter Trap, for example.
yes to the loser who put this!!
yes of course limit up to five
You can have 3 trap holes and 3 bottomless trap holes in a yugioh deck. That is, if you aren't playing in tournaments.
