You don't. Wiring is not "designed neat" with all the right wires of all the right colors coming into the box.
If you had OCD that absolutely required that, then I suppose you could get a dual switch (2 switches on one yoke) that had a common side, then you could supply "always-hot" on the common side and each switched-hot to the 2 screws. And then you would get a coverplate for your switch on one side and blank on the other.
But still, the white wires would need to be put back together. They are not "spare" (nobody puts unnecessary wires in walls) or "capped" (they were tied together so they could do their job). The fact you don't know this, with seeing different boxes as different, objecting to the pigtail, and expecting colors and wire counts to cooperate -- says that you see the right things, just need the book knowledge to fill in the holes. For that, you need a well-rounded primer on the subject: and for that, I recommend an actual book. Go to the library and see what book feels most accessible to you, and devour one. Google cannot serve as a substitute because it only answers questions, and you need a primer to know which questions to ask.
Once you're in the know, different things will bug you. You will want to know why the last guy didn't pigtail the always-hots on the switches. You'll want colored tape for marking wires by actual function, instead of taking the default manufactured colors.
Anyway, get a foot of black wire (solid, if in doubt #12) and a sampler pack of wire nuts. Ideal brand is electricians' choice.
- Put a 6" pigtail on one screw on each switch.
- wire nut all the neutrals together. If it falls off without tape, tighten more and use new wirenuts.
- wire nut the two pigtails with the black wire from supply.
- Mark the blacks to the lamps with colored tape (optional) and land them on the remaining screws on the switches.
Use screws, not stabs. When loosening screws, when they get about 3/16" out, they will start to resist turning. Stop: they are captive screws. Forcing them out wrecks the switch in many cases.
