Ideally get pinch weld adapters or hockey pucks for your jackstands.
Most pinch welds are stiff enough to sit cleanly on a flat-top jackstand, but ideally get an adapter.

Yah... Don't do whats in the first and last photo. That's a pretty sure way to bend the shit out of your jack points and its a miracle they didn't bend in those photos already. For pinch welds you need a pinch weld adapter or a jack stand designed for them. Same goes for floor jacks, you need the adapter to avoid destroying your lower body and pinch weld.
The other problem is lifting the car initially. Assuming you have the proper jack stands and not the ones designed for cars from the 1950's, Then you need to find another safe jacking point to lift the car onto the stands. You can't just jack a car from the lift point and poof, swap in a stand mid air and thats what op is looking for.
You can get rubber adapters for your jack stands to help prevent bending the pinch welds apart.

I've also seen guys use a length of unistrut along the pinch weld (the weld fits right inside the unistrut) and welded onto the jack or jack stand. There may be an actual purpose built adapter or jack stand that works that way.
I use a floor jack under one of the control arms then place the jackstand on the frame rail with these: https://www.amazon.com/dp/B07KFDM55B/ref=cm_sw_em_r_mt_dp_ASRWKYSTPW6Z8GTP8N9H
