If it is a 486, this will be 72 pin
Otherwise, it is 160 pin (or whatever that number is ;)

It depends.
A 386-machine needs 16-bit databus for RAM, so its RAM needs to be 16 bits
wide.
486 needs 32 bits
Pentium needs 64 bits
I don't know about the Pentium II and Pentium III for sure, but I believe
they need 64 as well.

If you have a (very old) 32 (but I believe it is 34) pin memory slot, it is
a 16 bit wide slot.
So, for a 386, this is ok and you may use 1 card for ram.
Some 486-machines, though, have 34 pin memory slots as well, but they need
32 bits in their data bus, so a single card of 16 bits is not enough.
Therefore, in a 486-machine with the 34 pin slots, you need to put 2 cards.
Same counts for Pentium processors with 72 pin-slots.

So, whether you have to put them in there by two depends on the width of
your databus (how much bits fit in it) and on the width of your memory slot
(how much pins)
