pnp answer
No. The PNP and NPN transistors are exactly opposite each other in polarity. You cannot just replace one for the other without redesigning the circuit.
NPN and PNP transistors function in essentially the same way. The power supply polarities are simply reversed for each type. The only major difference between the two types is that the NPN transistor has a higher frequency response than the PNP-because electron flow is faster than hole flow. Therefore high frequency applications will utilize NPN transistors.

The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
PNP is sourcing. NPN is sinking. You generally connect NPN to ground and your PLC(or any load)input. With PNP you connect to V+ and to your PLC. Your PLC (load) should have the same ground or V+. Sourcing (PNP) provides a path to +24DC generally. Sinking (NPN) provides a path to 0V DC.

diff. between npn and pnp transristor
NPN and PNP are transistor types. The difference in the way the layers of semiconductor material are doped with impurities.
Here what we do is, we use the simple inverter parts and make any gate using it as a primary module. inverter work as follows. This is made out of two transistors NPN and PNP when we give high input(0.7)(which is connected to the base of NPN ad collector of PNP) it stops the current coming from the PNP form going towards the input and make it go towards base of NPN. This F/W bias the NPN and V(CE) become 0.2V and then as V(E) = 0, V(C) become 0.2V. Which is logic low. When we supply logic low as the input current from PNP goes towards input and not to base of NPN this make NPN R/W bias and collector voltage have to choose the high value (Here my explanation is done referring to the picture in http://thinklikemalinga.files.wordpress.com/2010/12/iil-inverter.png?w=490&h=359)
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
NPN, PNP only classified to BJT, while FET classified as P-channel , N-channel
pnp
Switching is faster in NPN transistor than PNP. Because movement of electrons is faster than holes.
no
To save a decoupling capacitor & biasing resistors for the PNP.
