So I'm installing 1/2 and 3/4 copper water pipe, city water, ~60psi.
Question - how much can you safely bend the pipe without risk of
future failure?

Question for you: why do you think you *need* to bend it?

There are a few places where it has to snake around a bit. Maybe a 10
degree bend here, maybe 5 degrees there. Not much, but I don't know what is
"too much". If bending is evil, I can simply use some 135 degree "elbows"
(what do you call the 135 degree bent couplers?) to make the necessary
bends. I bit more extra work, but I'm happy to do that instead of stressing
the pipe.

I'm using thicker stuff that is "approved" for being used behind walls, I
forget the letter designation that goes with it.

My bender is for 3/4 conduit - can that be used with 3/4 and 1/2 copper?

In one place I have two hot water connections and three for cold water.
Whoever did this ran five 1/2 pipes up through the floor (and my girls
complain about what happens to the shower water temp everytime someone
flushes the toilet). I see no reason not to run a set of hot/cold 3/4 pipes
up through the floor (two pipes going up, not five) and then tee off as
needed once I get where I'm going. Simpler, cleaner, uses less pipe.
