Any paint will adhere to lead based paint and seal it. Latex is the easiest. The lead will not bleed through and is not harmful as long as it is not flaking off. It is only harmful if a child chews on it and swallows it.
Yes, you can. Use workable fixative or retouch varnish.
If the varnish hasn't already dried, I'm afraid the only way to conceal it will be to paint over it. If it hasn't, wipe it up quickly.
Start with a primer, Perma Seal is great. then I would use oil based paint.
Paint can be applied over varnish, but it needs to be a compatible type of paint for the type of varnish, and the surface needs to be prepared by removing loose material, dirt and sanding. If it is not a compatible paint the surface needs to be etch primed. Contact a local paint supplier for advice.
For oil paintings: best let it dry for a longer time (6 months or so), then put dammar varnish over it. The long drying time makes sure you can take off the varnish later, without harming the paint itself.
That is not generally recommended.
It will protect the paint as long as you use a water based varnish, never use oil based varnish over water based paint. Tip: "water based enamel= water based finish". "oil based enamel= oil based finish".

Yes, you can apply varnish over paint to achieve a glossy finish. Varnish is a clear protective coating that can enhance the appearance and durability of painted surfaces.

Yes, but I usually sand it lightly first.

Usually yes. You'd be advised to use a water based varnish, and rough up the paint a little before coating.
The crackelure (craquelure) on an oil painting are the small cracks that appear as a result of the paint and/or varnish shrinking.
Varnish preserves wood better than paint.
