What do the following questions mean:
(b)How many different OSCl bond angles are there in this molecule?
(c) What values are expected for the OSCl and ClSCl bond angles?

I believe different bond angles refer to how many different degree types are found in the molecule, such as 90 degrees, 120 degrees, 180 degrees, etc. The follow up question just refers to the values of the of such degrees in the molecule. I hope this helps!!

So for clarification, if the molecular shape for SOCl2 is trigonal pyramidal would the angles for OSCl and ClSCl be 109.5?

Yes, the angles would be 109.5 degrees for this specific molecule, however, molecules with trigonal pyramidal shapes have angles that differ based on the atoms involved in the molecule. For example, the ion SO3^2- is trigonal pyramidal, but the angles are actually 106 degrees and not the expected 109.5 degrees.
