If a molecule given has 2 double bonds and 1 triple bond, would the number of sigma bonds be 3 and the number of pi bonds be 4?

Yeah, that's correct. A single bond will have 1 sigma bond, 0 pi bonds. A double bond will have 1 sigma bond, 1 pi bond. A triple bond will have 1 sigma bond, 2 pi bonds. Using this reasoning, we can say that a molecule with 2 double bonds and 1 triple bond will have 3 sigma bonds and 4 pi bonds.

yes. One double bond consists of one sigma bond and one pi bond, and one triple bond consist of one sigma bond and two pi bonds.

Yes, that is correct for every double bond there is one sigma and one pi bond and for every triple bond there is two pi bonds and 1 sigma bond.

Yes. Every bonding region has one sigma bond. All additional bonds are pi bonds.

Yep! Every first bond is a sigma bond. Any other bond added on top of the first ones are considered pi bonds.

yes! a double bond contains 1 sigma and 1 pi bond while a triple bond contains 1 sigma and 2 pi bonds so just add those up!!
