Colin,
Almost all tipped tools already have the correct feed angle built into them, so they should be fed square in, either from the side (normal) or nose on.
Looking at the top row from left to right, LH cutting tool, for cutting left to right, RH facing tool, this is your normally used one, for facing off on the LH side, profile tool, next, no idea, but if it is a 60 deg angle, then maybe a threading tool, RH cutting tool, the one you will use the most, for cutting right to left, LH facing tool, for facing on the RH side, and lastly a boring tool.
