For example 1) I have positive delta options sold and negative delta options sold. The combination would look like this? Sold call delta .371 + Sold put delta -.245 Positition delta = -.126 ? 2) I have negative delta option bought and negative delta option sold. Bought put delta -.279 + sold put delta -.151 Position delta = -.128 ? Thank you for checking

You have two negatives in example 2, but that aside -- Yes: position greeks are additive for the same (underlying) contract.

you really should buy a basic book on options since this is really basic the way you put it's it's not understandable: if you are both short the call and short the put you have to add the short positive call delta (so a negative) and short the minus put delta (so both times a negative make a positive) in example 1 so that's -.126 in example 2 you most likely mean bought -.279 delta minus short put delta so that last one makes a positive +151 delta leading to position delta of -128
