You can love them, put rubber gloves on to put them in a case to display them and enjoy looking at them. You should have no problems then.
Bullets are made of lead, too.
It just occurred to me to check on lead poisoning in the military and I cam across this.

Shooting guns releases lead dust into the air, which causes lead poisoning. I never really thought about that possibility.
At any rate, these look like nice figurines. I would look at them being more archival than plastic figures, since I'm sure that lead figurines will remain intact for hundreds of years, as opposed to plastic, which can warp, sag, crack, and become brittle with age and break with age.
Unless you are going to handle these as part of enjoying them,and keep them in a sealed case, I would not be concerned about poisoning.
If you love handling them, though, you are in for a problem.
If you like them, buy them.
As an aside, did you know that all plastics leach a toxic gas called polyvinyl-chloride, that is carcinogenic? It is one of the reasons for that new action figure and new car smell. The hotter they get, the more they leach. It is why the insides or car windows fog up on hot days. You breathe that stuff into your lungs, which is very bad. Always best to open the doors to air a car out first before getting in on a hot day. Plastic poisons you without you even having to touch it.
Plastic water bottles in the sun? They leach carcinogenic chemicals into the water, which is why the water tastes like plastic. It tastes like plastic because you are drinking plastic.
Maybe you should buy real bronze statues instead.
Why be half safe?
